March 2017

"★ ★ ★ ★ ★ I moved out to CO a couple years ago and have been looking for a mechanic off and on as needed. I have now used them twice and have been very satisfied not only with the work he does but also with the price and especially his turn around time considering the work done. As a side note, my girlfriend was told she needed some work done and received an estimate. I recommended Mastermind and they did the work at a fraction of cost and fixed up another little minor thing as well. Highly recommended."

"★ ★ ★ ★ ★ What a godsend to find Mastermind Enterprises. I don't generally trust mechanics unless someone has had a good experience with them.

My daughter's 2004 PT Cruiser needed a clutch and a timing belt and all the accessories that go with them. Both are major jobs on this car with no room to work. They not only did the work they found legitimate items that also needed fixed that I would have missed. They kept me in the loop on eta of completion, needed parts and estimated cost.

I am truly pleased with the work they did and the way I was treated. The car runs like new. And now my daughter and granddaughters can travel safely. I would give them 5 stars out of 5! Thanks"

"★ ★ ★ ★ ★ When the cluch on my turbo PT cruiser went out I thought I would have to sell it and get myself wrapped up in a car payment I don't need. Thankfully, my dad found these wonderful people on google. They installed a completely new cluch and it runs like a charm!!! I'm also thankful they fixed whatever they came across while under the hood. When they had a order a part they expedited it so the car would be finished when my parents flew into Denver so we wouldn't have to make a special trip from Cheyenne. The price for all the work they did was decent. I would highly recommend this company to anyone who needed work on their car. Thank you for fixing my car!!!"

"★ ★ ★ ★ ★ We lost our long time mechanic Joe to cancer prior to us finding Joe we had a lot of bad experiences so we were very worried that we would end up having the same experiences. We did go one time to another outfit and were disappointed.

We found Mastermind on the internet so we tried them and now we are happy to say that we have found our replacement for Joe. Norm and Heidi are great people. Norm does great with our vehicles which we have 5 of. I would recommend them to all who need a mechanic, from small repairs to major engine repairs."

November 2016

"★ ★ ★ ★ ★ I had taken my ’98 Jeep Grand Cherokee to three other shops (a total of four times), none of them were able to identify the causes of my Death Wobble, but were happy fixed other things and charged me.

I was ready to trade it in, when I was referred to Mastermind. To my relief they identified and fixed the problem on the first visit. I have been driving the car for a month since without the slightest problem. I could not be happier. Norm and Heidi are very nice people to deal with.

Honest service at an honest and fair price. I could not be more pleased, thank you."

"★ ★ ★ ★ ★ I wanted to express my satisfaction with the repairs I had done on my car recently by Norm.

He found and corrected a very serious problem with my car’s front wheel drive train that Goodyear Auto in Broomfield and AAmco of Arvada had missed.

He also replaced the shocks/struts and front brakes at a very reasonable price and the repairs were completed the day I brought the car in.

I can’t say enough about how pleased I am with his work and the friendly help Heidi provided at the front desk.

Been telling everyone interested about finally finding a great auto mechanic and would recommend Mastermind for their car.

I’ll be trusting them with all my vehicle repairs from now on."

"★ ★ ★ ★ ★ I was referred to Mastermind Enterprises and couldn't be happier that I took that advice. When my fuel pump went out while driving, I had my car towed to their shop. Not only did I receive excellent service, Norm and Heidi were very helpful with a problem that occurred when the tow truck driver damaged the rear control arm on my vehicle. They went over and above taking pictures and sending in the paper work I needed to file a claim. I highly recommend. Great quaility, friendly and honest family business."

Review for Honest Auto Repair in Denver


"★ ★ ★ ★ ★ After an extensive review of this business, I took my 2003 Acura MDX in for what I thought would be routine maintenance. I anticipated having to spend quite a bit of $$$, but I received a phone call in which they honestly and thoroughly listed all of the items that needed to be repaired totaling $4k-$5k. Instead of just correcting my brakes, which was the initial reason I had taken the car in, and sending me on my way, they advised me to purchase a new vehicle because the maintenance needed for my Acura wasn't worth the money I would need to spend. Additionally, they worked with me on when I could drop off and pick up my vehicle. I appreciate a business that deals in integrity and not dollar signs. I recommend this company to everyone and have become a life long customer."

Review for Honest Auto Repair in Denver


"★ ★ ★ ★ ★ I have a Saturn that is nearly 14 years old. I've searched for someone who could reliably repair my car as needed (and it's more needed now that it's older!) and I've found exactly the right people in Mastermind Enterprises. I'm more than satisfied, I'm delighted with the knowledge, service and reliability they give. Around Thanksgiving 2015, the heater died. I tried a couple of places who said they couldn't fix it. Then I found Mastermind, and they fixed it perfectly. A few weeks ago I was in for an oil change and a "funny noise" in the engine. Turned out I also had bad brakes and a leaking radiator. They fixed all that for a very reasonable cost and I'm perfectly happy with the work and the warranties. HIGHLY RECOMMENDED!"

Not only did they give me a great deal on new brakes and rotors, but they were extremely friendly, honest, and kind people. They even let me know a great place where I can get my muffler fixed as well. I will definitely be coming back here for any repairs I need in the future! Awesome people, awesome service, and I would recommend them to anyone!"

Also they were able to get me back on the road in 2 days at a price that was lower than they originally quoted me. Thank you guys!"

"★ ★ ★ ★ ★ My experience with Mastermind Enterprises has been fantastic! I have had my car serviced at this location on two separate occasions and each time I have received service that has exceeded all expectations.

My most recent experience dealt with unknown knocking noise coming from the left front tire. Upon dropping off the vehicle, I anticipated the repairs to be extensive and costly. To my surprise the issue turned out to be minor and it was corrected quickly with little expense.

If you are searching for honest straight forward diagnosis regarding your vehicle's repair needs, I highly recommend taking your inquires and business to Mastermind Enterprises."

"★ ★ ★ ★ ★ Mastermind Enterprises did an amazing job on both our cars. We first took our Acura MDX to them in September. It needed a lot of work and we had been putting it off since the quote was so high from the dealership where we bought it. Heidi and Norm quoted us over $1000 under the dealership quote. They were thorough and efficient with repairing our vehicle. It has never ran better. Last week our other car, a Buick Rainier, unexpectedly broke down while my sister was driving it on the Intestate. We had it towed to Mastermind Enterprises after hours. We were expecting significant mechanic issues and a high cost in repair. Norm later called the next day with a very low estimate for repairs and would have it done by that evening. We found out it was caused by repairs another dealership completed on the vehicle previously. This vehicle is also running better than it has in a very long time. We will be bypassing any dealerships from this point on and going straight to Mastermind Enterprise. They are transparent in their communication. They won't do any work without confirming with the owners first. We are very grateful to have found a family owned, reliable, transparent mechanic who cares about their customers. Thank you Heidi and Norm!"

"★ ★ ★ ★ ★ About a month ago I brought my 2000 Jeep Grand Cherokee to Mastermind for an oil change & overall check-up. I knew there were some issues that needed to be taken care of. In the past I always took it to the dealer, which my husband wasn't thrilled with. He never seems to be happy with who I take it to. After the work was done my husband went with me to pick it up. Norm explained everything that he did and gave us recommendations that could be taken care of in the future. My husband was very impressed. We've taken a couple of trips around the state and it drives so much better. My husband even made the comment on how nice it drives now. I will definitely recommend Mastermind Car Services to anyone needing care repair. I trust them & they do a terrific job!!!"

September 2015

"★ ★ ★ ★ ★ Very helpful and honest staff. Norm has fixed my car several times and always under budget from original quote. Punctual returns of phone calls, and very informative with the state of your car. Extremely honest and do not try and sell you additional mechanical improvements for your cars. Very thorough without trying to sell you anything extra. Privately owned and operated so you can feel the family atmosphere. This business survives on "word of mouth" and reviews alone to promote there exceptional services and reasonable prices. For this reason, I wanted to take the time and accredit this company as a valuable tool for anyone trying to not be screwed by your typical mechanic.

I had an atypical wiring issue with my radiator cooling fans. After 2 other mechanic diagnosis and some self improvements and upgrades of parts on my own, I brought my car back to Norm (which I should have done in the first place). After taking a lengthy amount of time out of his day to diagnosis and power my fans alternatively (to see if they still worked), he was able to find the thermostat relay NOT working. Other mechanics suggested re-wiring the whole radiator fans circuits etc. Those estimates coming in at $500 plus. Mastermind Enterprises took 3 hours to access, diagnose, fix, and maintain surveillance on (running car with fans blowing) to assure the car's radiator cooling system would work properly. He then called back with a completed job, both faster than expected and extremely under budget from other companies quotes. I only had to pay $158 to have a completely functional car returned to me. If this was not enough, he also told me should this not correct the issue, they would credit me the difference on the next job to fix the issue. Very reliable and honest staff."

Review for Honest Auto Repair Shop in Denver


"★ ★ ★ ★ ★ This afternoon I was at Mastermind getting a variety of problems checked out. One involved a failing a/c compressor, installed less than a year ago. From the side of the telephone conversation I could hear, it was clear that the parts vendor was not going to stand behind its warranty. Norm turns out to run a business that will eat the cost of making things right even if he did not create the problem. This is why I keep going back there for all my auto work: Norm is an excellent mechanic, but, even more, Norm and Heidi have amazing integrity."

"★ ★ ★ ★ ★ Finally found a trustworthy mechanic. We had them rebuild an engine for us a year ago and have had no issues. Since then we have used them for a few unrelated repairs and oil changes as well. They even have a relationship with a car rental company that can pick you up when you drop the car off.

Good family business and Norm the mechanic is very helpful and detailed in what happened and what he recommends. I've been very happy with them."

"★ ★ ★ ★ ★ If you want it done right the 1st time and at a fair honest price than Mastermind Ent is your choice. We used another shop and for about 2 years tried various parts with no fix on our 2003 Chevy Impala. After just about giving up and thinking we would just sell it and move on we luckily came across Mastermind Ent and gave them a try.

What the other shop could not diagnose or fix for 2 years Mastermind did in about 2 hours. We feel like we have a new car and would recommend Mastermind to anyone. They get you in quickly and let you know exactly what needs to be fixed and explain it in easy to understand terms.

I look forward to using them in the future for all my auto repair needs--thanks for the amazing work--"

It's nice to be able to trust a shop again. I will certainly go back with any problems I can't do myself. Norm has the know how, and Heidi makes you feel welcome.

We were initially reluctant to have any more work done on this vehicle and inherently felt worried that we would be taken advantage of once again. Heidi and Norm immediately put us at ease with their professionalism, knowledge, and honesty. Our car is running perfectly! We will definitely be returning for all of our auto repairs in the future! I would highly recommend Mastermind to anyone looking for an honest and caring shop."

"★ ★ ★ ★ ★ After receiving service from Mastermind Automotive I would recommend this business to anyone looking for an honest and thorough assessment. The car was worked on by Norm, a dedicated, hardworking individual who offered an honest and beyond reasonable assessment of the damages and necessary repairs.

If you are looking for a great place where you can rest assured that your car will be competently repaired in a short amount of time, without additional unnecessary work being done, look no further."

"★ ★ ★ ★ ★ I feel lucky to have found Mastermind Enterprises. They replaced my clutch last fall and also found that my timing belt need to be replaced...instead of having to make two different trips to get them fixed ME saved me time by getting it all done in one day.

I will continue to trust them with my car maintenance and will definitely recommend them to anyone!"

Review for Saving Money on Replacing Timing Belt and Clutch Repair in Denver


"★ ★ ★ ★ ★ First, I want to say that I am so happy that we found Mastermind Enterprises. We recently bought a used car 3 months prior and it was working fine until it stalled on my husband on his way to work. He called our insurance company and they towed it to Mastermind Enterprises. My husband called and told me that they fit him right in and offered to do a full diagnosis of the car. They gave us a call back pretty quickly and gave me the price for the repairs.

Honestly, I was a little skeptical because we have a mechanic that we have used for 6 years and I did not really trust a place I have not used before. I even called our mechanic and they were going to be $400 higher for the exact same work. Heidi walked me through what needed to be fixed to make the car run (an new Crankshaft position sensor) but then gave me an option to fix the timing belt and all the pulleys that are located right in the same area....which saved me an additional $418 in labor. Our car had 80K miles and this work really should have been done around 60K miles.

They are genuine honest and courteous people. It is so rare now days to get what you pay for and I believe Norm and his family are the way people used to be....honest, friendly and respectable. It truly is hard to find REAL people in the business world today that will go out of their way to make sure things are done right. Thank you both for helping our family in this terrible situation.

Review for Saving Money on Auto Repair in Denver


"★ ★ ★ ★ ★ Mastermind Enterprises saved me over $700 dollars!! I got a quote from one company who couldn't get my car done until next week so I called other places and came across these guys. They not only were able to diagnose the problem the day I called but had my car fixed, running and ready for me to pick up all before they closed that evening. They also have a great towing company that has very affordable flat rates.

The customer service was awesome and they were very knowledgeable; showed me exactly what was wrong and explained what happened in a way that I, a non-car/mechanical person at all, was able to understand. I would highly recommend Mastermind to all of my friends!"

So glad to find a shop that keeps their promise and does not sneak in extra charges when it's time to pay. We have been back to have an engine light condition checked. Norm & Heidi worked together to diagnose & order the part needed and get us back on the road.

"Norm and Heidi have been great to me and my 97 Jeep Wrangler.

After a rough trip on Thanksgiving of last year I needed a new transmission in my Jeep and Norm followed up with me the same day. Both he and Heidi helped my family and I through deciding on what part to purchase for the Jeep and he was able to repair my Jeep within two days. Ever since then I have been going to Mastermind for anything from a basic oil change, to more hardware repairs and I went by to get a basic inspection when the Jeep was acting funny. Every time I stop into Norm and Heidi's shop, they are both welcoming and are genuinely invested to how I am and how the Jeep is.

Their family business is incredibly efficient, timely, and honest. I respect their service and I feel blessed to have found a loyal auto shop for my Jeep.
I'll be taking my future cars there as well. Thank you both!"

Although, they could fix my car, I chose to move on, I owned my car for 15+ years. They referred me to a guy that offered me more money than other companies that advertise "we buy junk cars". Thanks for the wonderful experience, and I will be back for all of my car care needs. You're Awesome!"

"I took my car to Mastermind Enterprise earlier this week and was comfortable the minute I walked in the door. I was greeted by Heidi and her children when I came in. Right then I know I had picked the right place. She was super friendly and talked to me in a way that instantly put me at ease.

As a young mom of two I always feel like I could easily be taken advantage of when it comes to dealing with mechanics. I did not feel that way at all here.

They know how important and vital cars are to people and they are quick affordable and honest. I would recommend this place to anyone having car trouble.

Thank you so much Norm and Heidi I will continue to bring my car to you guys! "

"I'm a female, and going into mechanics alone has always been frustrating. I'm usually fed full of s*** and told I NEED to spend $1,000 now to save my car. But here they spent time with my jeep, were honest and said my jeep wasn't on the verge of breaking down. I did the research into what they said and after 6 shops in one week trying to diagnose the problem these guy hit it right on the money and weren't greedy or pushy about the expensive unimportant fix.

I will return to this shop if I have problems. I would suggest this shop to ladies. It's so hard to trust a mechanic as one."

"My family and I were traveling in from Austin, Texas when our check engine light came on. I stopped myself at an auto parts store to see what it might mean. I was on vacation and didn't know what to do myself. A friend recommended this place and I was afraid I was going to be paying more then I thought thinking my warranty was not going to cover the issue with my vehicle. Norm even referred me to the website for a coupon to help out with cost.

Our experience here allowed our vacation to go on without worry. I wish they were in Austin. These would be my mechanics. At least my local family has a place to trust now. Recommended even from Austin, TX. TRUST THEM, THEY WILL TAKE GOOD CARE OF YOU."

"I have been using Mastermind for several years now. There is no one I would feel more comfortable trusting my vehicle maintainence to. With Norm as your mechanic you know you will get an honest and accurate diagnosis of the problem at a fair price. He will also bring to your attention problems outside of what you asked him to fix. Just things he notices or knows are common problems on that vehicle make. I never feel like he is looking for ways to squeeze more money out of me. On the contrary, he does his best to save me money where he can.

No matter how busy his day is going he will spend all the time necessary with me until all my questions are answered and I understand what is going on with the vehicle. This is not a franchise where they want to get you in, upsell as much as possible, and get on to the next customer in a hurry.
Mastermind is the auto repair shop that you stay with because you know it will never be better anywhere else."

"Great people, Quality Auto Repair & Service...AND Great Prices, too! I took my my 2003 Hyundai Santa Fe in for a timing belt and water pump replacement service after a call to let them know I was on my way. I received a call a short time later with an estimate for hundreds less than other shops and dealers in town. I had to double check and do my research because I like to save money, especially on auto repair. My estimate from Mastermind Enterprises also included ALL of the timing belt parts (I didn't now there were so many parts that support your timing belt!), water pump and coolant, not just the belt and water pump like the other shops.

I FINALLY found an honest, friendly, quality auto repair shop in Denver that I can REALLY count on! I am now a customer for LIFE! After that wonderful experience and learning that I had gotten lucky with my 2003 Santa Fe because I went over the recommended mileage for replacement, I returned to Mastermind Enterprises again with my 2007 Hyundai Tucson for a timing belt and water pump service and got another great deal! I double checked the price after the service and found I saved $100 or more than taking it somewhere else! I also learned a lot of how and why my timing belt service is SO important for the long life of my vehicles.

After horrible experiences with multiple other shops and dealers in Denver, I am SO happy to have found a great family owned place that I can trust, enjoy coming to, AND SAVE MONEY! The office is clean, the people are friendly and my 2 young sons LOVED the great fish tank! Getting my car serviced is now a pleasure! These people can be trusted with my vehicles anytime!

I am telling all my family and friends about this great shop in Denver! Thank you, Mastermind Enterprises! Keep up the great work! We will see you next time!"

"I have never written a review for Yelp before, but my experience at Mastermind Enterprises was just to great not to give them a thumbs up.

I took my Kia in to mastermind as I was told by another mechanic that I had a short between the blower motor and the relay. I was expecting to pay $300-$500 to get it fixed. When I was driving over to drop the car off, I hit a bump and the blower came on. When the mechanic called I was told that he weren't sure what the problem was as the problem was hard to diagnosis due to the fact that the blower was working at the moment. He said that he had replaced a connector; he thought that was the problem, but couldn't guarantee it. When I asked about the charge, I was told there would be no change as he thought he had fixed the problem, but wasn't positive. Wow that really surprised me.

An honest mechanic? I would have to say yes. It has now been 4 days and the blower is still working consistently, instead of working sometimes and not others. Although the shop is many miles from my house, I will be taking it to MasterMind from now on. They have even teamed up with Enterprise car rental to give you a great disconnect on a car rental while they fix yours.

Honesty, customer service orientated and friendly what more could you ask for?"

Met both the owners...friendliest people ever........cleanest shop ever.......this place is a stand out class act. I encourage everyone in Denver or traveling thru to make a point to at least have them check out your vehicle. Worst case scenerio you will walk out with an HONEST opinion. If only yelp would allow me to rank 6 out of 5 stars. Nissan runs great."

Norm will tell you exactly what's wrong with your vehicle and then give you all your options. He'll tell you what has to be done, then what else should/could be done without trying to up-sell you.

They're also amazingly fast and accommodating. I brought in two cars - both were diagnosed within the hour. One was fixed and running great by the next morning. The other was totalled, but they even let me keep it in their lot for days while I figured out how to haul it away. Thanks Mastermind! Will be back."

"I have known Heidi and Norm Olsen for 11 years now and must commend this young couple for the hard work they have performed to establish a loving home environment and a successful business.

What makes them different than the others, from a business perspective, is the way they are always eager to assist individuals/ customers with auto needs and concerns. Whether its questions that need to be answered or a service that needs handling, they are dedicated to providing the very best.

Norm is a walking encyclopedia of knowledge, as well as a highly skilled mechanic that takes his service reputation very seriously. His honesty and passion for excellence reflects in the quality of his work and you can walk away knowing that your vehicle was either maintained and or repaired with good hands. Hats off to both of you…"

"I just wanted to take a moment and say what a great place Mastermind is to service any vehicle. I started taking my 1999 Dodge Dakota for service work a few year's ago and I'm so glad that I did.

Norm is the most honest mechanic that I've ever found and he does "Very High Quality" work. I drive a pretty good distance to work every day and need my truck to be in tip top running condition and he makes sure that my reliable old beast stays that way.

I would recommend coming to see what quality service really is so call Heidi and you won't be disappointed. They are a family owned business and they treat all of their customers like extended family which is awesome! I've been to many mechanics in the past but I've never felt so at ease as I do when I bring my truck in knowing that I'll be given a fair price for superb workmanship.

Fire the mechanic you have now and swing on in to see them!!"

"After moving back to Colorado from California I needed to find a decent and respectable not to mention an honest mechanic. After a detailed research for a mechanic and believe me I did a research that was so in depth I made the decision to with Mastermind Enterprises.

I have a 1998 Jeep 4x4 Sport, I needed a tune up it was making a Loud noise and I not knowing a thing about cars (I had a mechanic as my best friend in CA). I called and spoke to Heidi she quoted me a price and that price was in the price range I could afford, I took the Jeep in met Heidi and her husband Norm (great guy). Norm tuned up my Jeep and found the root of my Loud noise, he actually showed me. Because I am one of those type of people I need to see the reason and BOOM! There it was...

I will be taking my Jeep back to Mastermind to have Norm service it from now on, I have truly been Lucky to find
"My Mechanic.""

Inspiring me to give them another well deserved 5 stars, and to hopefully assist those that are searching for a repair center. I plan on taking the Vue back for the basics too.

The second sudden death of my car came from a faulty component. No fault of mine or the shops. The maker of the part wanted me to pay upfront to fix the vehicle and then file an assurance claim with them. Norm stood by his work and took the claim to the manufacturer himself! No, really. He took the claim to the manufacturers. I can't recommend them enough."

"Mastermind did yet another great job on my car today at a moments notice!"

- Kristy A. Anderson
Denver, CO


"I left Denver with my daughters Oldsmobile Regency which Mastermind just fixed. It had an array of problems. Thanks to Mastermind, I had a wonderful drive back to Ohio. It ran like a dream. I only had to stop for gas. I did check oil and coolant each time I stopped for gas and it used none.

Norm and Heidi were very proffessional and a pleasure to communicate with. Thanks Mastermind"

- Herman


"I was tired of dealerships and dishonest mechanics so I searched for a place where I was more than just a number.

Luckily I found Mastermind and now I won't take my car anywhere else. I'm always satisfied with their superior work and the price it cost me. Very grateful I found them!"

- Janet

"I have to travel 100 miles round trip for mastermind to do my auto work - and I doing it very willingly!

Honest, salt of the earth, family owned and operated - it is a pleasure doing business with reliable and professional people that really care about doing the right thing by their customers! Thanks Norm and Heidi!

"Norm and Heidi has always been honest with me. I love that and they fixed my car when another Napa Auto Care Center out of state failed to locate the problem that ended up costing me a lot more in the end. Norm fixed it right away and I am glad to have an honest mechanic again. I have been spoiled by their honesty and great work.

A honest mechanic is very hard to find but im glad I found them. They also worked with me to get things up and running and driving safe on the road. Thank you so much you guys."

- motheroftwo

"Finally an honest mechanic who knows what he is doing. Norm has done extensive work on my Chevy S10 as well as my wife's car. I feel confident when I leave my vehicle with him that it will be fixed correctly. Both he and his wife are friendly and easy to talk to. They have gone out of their way to finish my truck in a timely manner even when it needed large repairs on short notice. Their prices are fair and the work they do is outstanding!"

- Stephen

"We have finally found an honest mechanic who we can trust to do our vehicles without the worry of being over charged or diagnosed improperly.

"Mastermind did a great job on a really big job (replacing the motor) in my Mitsubishi Montero. I shopped around quite a bit and they came to me highly recommended from knowledgeable people. Their service did not disappoint.

They kept me up to date of what was happening with the car and their price was reasonable. I would highly recommend to anyone looking for a good mechanic."

"Norm and Heidi are exactly what you need to maintain your vehicles. A small professional shop with great customer service. Drive past the dealer, save your money, and know who is working on your vehicle.

I first came to them with a blown out engine and was skeptical at first and they've exceeded all my expectations. It's great to finally have a shop that I can trust"

- Matt Ander

April 2011

"Norm is a talented and driven tec with an eye for prefection and detail. To me this means a lot as my father left me my awesome 92 Ford F150 when he passed away and so I dont just trust anyone with this truck!

Recently I have had issues back and forth with my drivers inside door handle. These folks took the time, at no cost to me, to try and fix the internal parts of the door handle that was causing this issue an not just jumping right to replacing everything at the top dollor. It was only when my parts were confirmed broken that they were replaced and the cost to me was minimal compared to the dealer and even in my own time trying to figure out what was going on. These folks are great and the end work and detail shows for itself in who is working on your automoblie.

I recommened Norm and Mastermind to all my family and friends."

Thank you to Norm and Heidi at Mastermind for all of their help and awesome Customer Service. Thank you guys."

Denver, CO


"No exaggeration, Mastermind's the best shop I've worked with. Ever. I really admire the honesty and efficient estimate as well as the work that was done. No typical auto-shop push and shoving and Norm and Heidi even went out of their way to help me.

Fantastic job on the repairs! My car is running super great, whereas a month ago, I was praying to not get into an accident because of my damages."

"Norm tackled the daunting task of not only re-powering my heirloom '72 K/5 Blazer, he also installed a complete Holley Fuel injection system! I found all the work he did to be as meticulous and perfectionist as the finest restorations/conversions.

Norm and Heidi should have their own reality show based on their business! That'd show the rest of them how it's done! I can't say enough good things about the work ethic, honesty and integrity at Mastermind Enterprises."

- John
Denver, CO


"Mastermind is an excellent shop with reasonable rates, above and beyond service. Norm has been my mechanic for 10 years and counting.

When I first met Norm he was a mobile mechanic working out of his utility van through all elements and junk cars including mine. He now owns and operates his own Napa certified shop and is a certified master tech. Professional atmosphere and classy company. I DON'T trust my vehicle with anybody else.."

- Big Ron
Arvada, CO


"You wanna hear how great Norm is? The last car in this photo was sitting in a field for 12 years. The owner could not get it started to save his life. Turns out, someone put sugar in the gas tank. Norm cleaned the gas tank, fuel lines, replaced the fuel filter and throttle body after his diagnosis. After that, it ran beautifully!! Thanks Norm."

Most honest and helpful people

"Norm and Heidi have been very helpful, they have always made sure that our cars were running correctly and when i had a problem they fixed it right away, i have never heard of a mechanic having a warranty on his labor for a year, well it was true there was a part that went bad within the year it was replaced free of charge.

We had a history of going through Oil pans on a 2000 passat, Norm had recommended that we have him put a skit plate on, it worked great, lets just say we werent in every month for a new oil pan which was like $500 each time because the oil pan was so expensive because it had to come from the dealer, there was another car that they had worked on for us, there was a electrical short at our cruise control box on a 90 acura, my ex had taken it in about 4 or 5 times and they only replaced the alternator or the battery which were the things that were dead but they never found the problem, Norm did, I have recommended them to my family and I will still go to them, they are awesome people, honest kind, and seems like they have been there through the good and bad times with the cars and in our lives, they actually care and do not look at their customers as a Dollar sign which some mechanics do, thanks you guys,"

Best shop you'll find!!

"Norm and Heidi have not only been friendly, honest, and accurate with all their quotes and work, but the work has been done perfect and thorough every time!

My '07 Silverado and my wife's '01 Escape have been in there a couple times each for oil changes, shocks/struts, broken bolts, etc. They really treat you like you're a person, not just another invoice. Norm's awesome about (instantly) diagnosing the problem, and talking about what your options really are, not just the "replace this, replace that" bit you get elsewhere. Highly recommended, they've got ALL my mechanical work in the future!!

- Brandon Kuglin

"I am a traveling musician. I put a lot of miles on my car. I was referred to Norm and Heidi's shop by one of their long time customers and I came in the morning. He opened the hood and within seconds identified that my motor mount was bad and was causing my car to vibrate when I was in drive with the brake on.

I got great service at really good price! I would highly recommend anyone that needs auto service to come and see them!"

- Jerry Wagers

"Mastermind did a spectacular job on the sping coil conversion on my '03 Range Rover. Not only did they save me bundles, but I now get a better ride out of my vehicle. Furthermore, I never have to worry about any problems with air suspension again. Thanks!"

Westminster, CO


February 2010

"A couple weeks ago, I got in a jam with my 4runner. I was leaking axle fluid from my CV's and because I have a lifted truck, not many shops would even touch the car. Norm and I talked over the phone and referred me to CVJ who do some pretty cool stuff with Neoprene CV boots, which are more flexible and more heat resistant than rubber ones. So I brought the 4runner to Norm who did a great job on it. He pulled the axles had them picked up by CVJ who put the better boots on the 4runner and sent em back to Norm who put them back in the truck.

In a really stressful situation, Norm and Heidi were there to put my nerves to rest. I had 3 shops refuse to touch the 4runner altogether and one quote me almost twice the price that they did, and one shop that said they could get me in in a week or two. Norm and Heidi bailed me out of a jam and got me my car back the next day.

With a 3 year old to cart around and the need for my toyota to run like my toyota should, there was no one I trusted more with my car that week. I felt like Norm would treat my truck like it was his and he did. Even gave me some other suspension advice... Basically, Norm and Heidi went the extra mile to make sure I was taken care of and had piece of mind. You dont get that in many places. You do at Mastermind!"

"after taking my vehicle to other mechanics and not having my oil leak fixed or even properly diagnosed I can say that I surely will be coming back when I get up the dough to get my rear main fixed --- once my clutch needs to be replaced of course!

thanks a lot for everything! cool fish tank: check - awesome automotive repair: CHECK!"

- Ryan Nash

"i am so glad we have Norm as our mechanic, we had taken our Acura to other places just to spend money on the same thing over and over again, finally Norm had found the short and fixed it now my Acura runs great even after the gas tank issue that we all ran into after driving it, on the other hand he has done alot of work on my P.O.S. Passat lol, they have taken care of us and after going through 5 oil pans prior to norm, he had built a custom skid plate to help reduce the number of times we were replacing the oil pan and it went 9 months before we had to replace it again and the oil pan is not cheap but made like it.

Thanks Norm and Heidi for all your help!!!!"

December 2009

"I've been into cars all my life and Norm is the 1st and only mechanic I've ever met whom I trust through and through. Not only does he THOROUGHLY know his stuff, he's HONEST about what your vehicle needs and doesn't need. Plus, he tackles the tough jobs! I don't think anyone else would take on my hand-me-down '72 K5 re-power (and re-tranny, brakes, steering, and umpteen other odds and ends) WITH an EFI retro-fit (!), but do such a thorough yet surprisingly quick job as well! Thank You Norm!

To everyone reading these testimonials-this is the mechanic you've been looking for all your lives! Congratulations on finding him!"

I will have all my vehicles serviced by the Mastermind. While I waited Heidi made me feel right at home. I waited in there waiting room and had a soda pop and watched televison in a quiet setting. Thanks Mastermind Enterprises. See you next time."

"Honest people who are good at what they do! Talking to Norm about technical issues with my car actually feels like a normal conversation.. as opposed to talking to a con artist trying to bury you with technical jargon. Dealing with Heidi is always a pleasure and you leave feeling they both are trying hard to do the most good for your car and your wallet. They have definitely earned my business and I will be bringing my car from here on out."

"Exceeded my expectations! Thank you so much for your maintenance check of my 2008 Mercedes C300 sport; I spent around $400 at the dealer for my first check, and knew I could find a better deal elsewhere.

Not only was my car serviced more quickly and courteously at your facility than at the dealer, it was also more thoroughly checked! AND, I saved a bunch of money. Simply a no-brainer; thank you so very much! I will be back for any automotive needs we have of course, and I plan on spreading the word!"

- Gretchen Swanson, RN BSN MSN

"Heidi and Norm at Mastermind Enterprises are a good team, and they always take good care of my car. They stand behind their work, as they did with the struts I got through them. I've been taking my car to them for probably three years now, and I've never had any problems with their work."

- Tom Kuspiel
Denver, CO


"Mastermind Enterprises is definitely a winning choice when you need your vehicle(s) serviced, whether the service you require is just routine maintenance
(oil change, brakes), or in-depth analysis and service.

We have 2 vehicles which have been serviced at Mastermind Enterprises.
I brought my vehicle to Mastermind Enterprises because it "wasn't running right." Norm diagnosed the problem as the timing belt. By catching this early, Norm saved me from major problems and cost that I would have encountered had the timing belt broken! Because I knew that Norm did good work, I had him replace the clutch in the same vehicle. The vehicle runs GREAT! I brought my wife's car in as well, to have the timing belt replaced. We also have the routine maintenance performed on both vehicles at Mastermind Enterprises.

With Norm on the mechanical side, and Heidi on the clerical side, Mastermind Enterprises provides honest, superior service as far as scheduling, quotes, and the actual work performed. My wife and I would recommend this company to ANYONE who requires service on their vehicles."

- Steven & Tracy Smith

"Our company truck runs awesome! Norm did really good with the diagnostics. He went more into detail than I thought he would, more than anyone else. Normally, other shops just pinpoint the problem, they don't go through the whole truck like Norm did. The truck runs great! It has more get up and go! He did a really good job!"

"In all my 35yrs of living I've never met a couple so kind, honest and professional. The Olsen Family are a Class AAAA team. Norm with his Honesty and Master Expertise coupled with Heidi and her Genuine Care and Professional Class make doing business with them seem like going to visit Family and Friends. WOW!!!!!! What a BLESSING !!!! MASTERMIND ENTERPRISES is #1 in service, price, dependability and customer satisfaction HANDS DOWN!!!! If you don't believe me just call me for yourself. Believe it or not this is my first ever testimonial for any company and that's because the experience I had in doing business with the Olsens compelled me to try in someway to return the favor or better yet the "Blessing".

Thanks again Norm and Heidi aka "Team Olsen" your the BEST in the BUSINESS without a doubt."

August 2009

"I'm a new customer of Mastermind. I haven't been happy with dealer service shops and even some local smaller shops that have layers of administrative personnel.

I chose Mastermind because it's family owned and I was able to speak directly to Norm, who is the owner and serviced my car. Norm and his wife, Heidi, are really friendly and not aggressive at all.

In a world where fairness and customer service have been forgotten, especially
in the automobile repair industry, this place shines in my book as #1. I think this business is outstanding and should be supported. That is why I took the time to write this review."

- Keith
Louisville, CO


July 2009

"First off I'd like to say THANK YOU so much to you both. Norm and Heidi are kind and caring. So, my story goes like this. I bought a 1987 Toyota Supra a while back. So, I did what every young adult out there is doing. I wanted to modify my car. So I took it to a performance shop and after $10 grand or so in bolt on parts for my car the shop's owner stole all my parts and destroyed my engine :-( Then, I found my car at a impound lot because he closed down shop and took off. I lost a lot of money and time.

So, after thinking about my options either junk the car or spend more money and fix it. I found a light of hope when I found Norm and Heidi. Norm helped me on every decision and saved me lots of money, even though my car has been with them for a very good while now. Norm hasn't changed his estimate.

Thank you so much again. My girlfriend and I are so happy to have made friends with both Norm and Heidi, we enjoy stopping by everytime we get the chance to spend time with Norm and Heidi. Norm and Heidi make us feel right at home, and to have another great couple to talk to and hangout with is so awesome.

There aren't enought words in the english vocabulary for me to express my appreciation to great friends
(Norm & Heidi) the masters of
Mastermind Enterprises.
Thank you again!"

"Going to Mastermind should be your master plan to have all your services done on your car. I was referred by a co-worker and haven't been back to any other service place or back to the dealership.

Norm is always open to listening to my thoughts about what my car issues are and gives straight forward answers and options if there are any. When it comes to things such as upgrades, add-ons or alternatives, the guy knows his stuff and is even creative to help see your idea through.

Overall customer service from Norm & Heidi is top notch! You would think the way things get done that there was a whole staff!

They are friendly and work hard to get whatever is needed to get the job done and your satisfaction."

Auto Repair Customer Satisfaction is our #1 Goal in Denver!


June 2009

"I had just purchased an Audi and decided to give Mastermind a try after reading their customer compliments on their website. I am a skeptic but I decided to give them a try.

I am glad to say that that the service I received was that of sincerity and honesty on their part. It was determined that my car needed a cap & rotor and all of my belts were shot! Norm told me that I did not need plugs & wires only a cap replacement. Norm could have very easily told me that it needed a major tune up, but he did not.

The service is professional and friendly, just as advertised. My car runs like a totally different car thanks to them.

I'll be coming back soon!!!"

- Al

Thanks Norm & Heidi."

"Epic customer service. Mastermind could prove even the most automotive-oriented mind feeble in skill. I tip my hat to Norm.

I never knew such graciousness existed and I am eternally thankful to have been served so well. You have truly embodied a style that is extremely amicable. I highly recommend Matermind Enterprises for anyone that has to deal with automotive issues.

Thank you Norman and Heidi. It has been a real pleasure."

"A few weeks ago I took my van into Norm's shop to see if he would be able to replace my ball joints and shocks because I was having severe steering problems. Norm took a look and said it would be no problem.

My concern was that since my van is used for my commision based business, I couldn't have it down too long. Norm said he would be able to get my van back to me the same day. True to his word, Norm called later that day and said my van was ready to go. Not only was the time frame perfect, but the price was great too.

I really appreciated his consideration regarding my need to have the van back so quickly. He delivered exactly what he promised. I recommend Norm to all my friends and will continue to do so!

Thanks again for your excellent service!"

- Mark Mohr

"I was just about to sell my car for a loss and then discovered Heidi and Norm at Mastermind. With a brake light that wouldn't turn off, a headlight that wouldn't work and other similar issues, it seemed like an expensive electrical job was at hand. It turns out that I had improperly placed the bulb and the master brake cylinder needed a fill.

I got an honest assessment and he fixed everything in an hour! I was then able to sell the car for fair market value. "Thank you" Heidi & Norm, you have a great family owned business and I will definitely be back!"

- Patty Springmeier
Denver, CO


"High quality service by people who care" is truly how Norm and Heidi conduct their business. In a world that is motivated by money, it is hard to find a business that puts people first. Norm and Heidi truly provide a high quality service keeping people their first priority. I have used many car repair shops and ME is the only one that I can fully trust and recommend to friends and family."

- Nancy Cristadoro

"Talk about dependability! These guys are on top of their game. Yet, there is no game-playing to be found. Just honest, reliable, trustworthy service, at a price one would expect to be much higher than it was. I never expected to find the best price in town AND the best customer service and mechanical work combined!

My only worry is that the next time I need work done on my car, they will be too swamped with customers to get me in instantaneously; that the best-kept secret in town is about to become no longer a secret. I am convinced that the service and value will be well worth the wait, regardless. Thanks you guys!"

"Norm has been my mechanic for years and I tell everyone about him! I don't know a thing about cars and Norm has been nothing but honest every time I have a question or concern. Sometimes he even tells me I don't need anything done.

I would trust him and his wife with my daughter, so of course I would trust them with my car. If only I had a hairdresser I loved this much!"

- Miranda McKinney
Arvada, CO


"Norm Olsen has been my mechanic since he first went into business; I may have been his first customer. I found him through happenstance; but I've stayed with him through the years for this good reason: One can find a skilled mechanic. One can find an honest mechanic. But it's not always easy to find a mechanic whose skill and honesty both you can trust.

Norm has done work for me ranging from oil changes to a complete engine rebuild. In every case the work has been well done; and, more to the point, in every case Norm has discussed thoroughly not only what needs to be done and why, but alternative approaches from the minimalist to the ultimate, and helped me choose the one that is best for me in my circumstances at the time. Then he does what we've agreed on.

Executive summary: Norm knows what he's doing, and he will work with you."

- Gary Williams

"I have used this company for several years now. It is very comforting to use an honest, reputable business that stands behind their product and provides a very competitive price to begin with.

If you are looking for a company to do the job right the first time without problems, without callbacks, this is the company I would recommend!"

- Rick

"It is so wonderful to finally have a shop and a great mechanic that I can trust.

Everything is done in a quality manner by a certified mechanic for less than the dealer and most shops. The thing I liked most was that they keep there promise relative to their estimate. Twice the work was more, but I was only charged for the estimate.

Best Mechanic I have ever had."

- Doug Koss

"After getting several quotes and varied advice, I found Norm and Heidi's ad.

Norm knows his stuff and they were both friendly, honest, and helpful all the way from getting my truck towed out of my driveway to giving me my keys with it running great.They treated me like a person, not a dollar, and showed appreciation for my business. The only other mechanic that would have treated me this well is my dad's best friend. Glad to find a great mechanic w/o driving out of the state.

God bless."

"I just wanted to take a minute to thank Norm and Heidi for their excellent customer service.

Unfortunately my mechanic moved away last year, so I had to find a new one. After 2 very bad experiences with not-so-honest, shops I ran across Mastermind's ad online.

I actually had an unusual issue with my boat. What seemed to be a relatively simple problem turned out to be a big hassle. I spent hours on the phone trying to find someone who would even take the time to look at it. Finally, I got ahold of Norm and explained the situation. He not only said he'd look at it he said he would "take care of it" for a very reasonable price - no matter what he had to do. This is after I had been told more than once that I would have to remove my motor before anyone else would look at it!

He was true to his word and my problem was finally solved! What impressed me most when I went to his shop was the time he took to let me explain my issues with other mechanics this summer. I was basically venting but Norm was genuinely interested.

I've since had Norm do work on my truck and not only did he do the work but he also corrected an issue I wasn't aware of at no extra cost. I'm glad I finally ran into someone in Denver who takes care of my vehicles the way he takes care of his own! He's a self-admitted perfectionist and I would recommend him to all my friends and family. Norm takes the time to listen and he takes the time to do the job right."

"I found Norm through Craigslist, and spoke with Heidi after emailing them about my clutch. They were not only quickly responsive, yet even willing to help me with my emergency repair on a Saturday!

Quite simply, if you're looking for the
"best of the best" in a certified, ASE Master Technician, look no further!

They saved me nearly $200.00 over other mechanic's estimates who were not nearly as qualified, and to meet and get to know them was a great experience for me, as they are friendly, professional and family-oriented with an exceptionally clean and warm service center, a comfortable lounge, and reception area!

I was involved with franchised dealerships' Customer Service for over 20 years and felt the same level of comfort there as I had with any Mercedes Benz or Lexus dealership!

Wherever else you go to get an estimate as I did, remember to get to them last before making a regrettable mistake!"

"Hello, If you are reading this testimonial it means you are considering having some auto work done at Mastermind Enterprises. You could not make a better choice for any of your automotive needs.

I have been a client of Norm's for over six years. He has worked on three different vehicles all of which are older models. When I first met Norm, he was engaged in a mobile service. Ever since, I have made it a point to continue to use Norm's services regardless of where in the Denver Metro area he has been located. I will not take any of my work anywhere else.

Norm is the ideal mechanic for someone like me who has a limited mechanical aptitude. He takes the time to explain what is needed in terms I can understand. He makes sure that all of my questions are answered. He gives fast, reliable estimates. There are never any "hidden" or "forgotten" fees or charges. Norm does what he says he is going to do, at the price he quoted and he stands behind his work. I hope that Norm will stay in business for many years to come. I will remain a happy customer, so long as he is there to take care of my autos.

If you have any questions about this referral or my experiences with Mastermind Enterprises, please feel free to contact me at Be sure to reference this testimonial in your subject line."

"It's hard to find a mechanic that has integrity and works with a moral compass. Norm is not only a great mechanic, he is an honest person who truly treats customers the way he would like to be treated. I am extremely pleased and will never go to another mechanic again.

He and his wife make a great team, and they are some of the nicest people I have had the pleasure of meeting."

"Norm is a hell of a mechanic. Had my car running several times after I thought it was time for the boneyard.

Genius, I believe the name of the company says it all!"
