Some POS stole our catalytic converter from our RV. We were about to leave for a trip. I contacted David and he got right on it and ordered our cat. He went above and beyond and got on us on the road on time. David is an honest mechanic and a really nice guy. I couldn't recommend him more. read more

DAVID of DNA services has been very forthcoming with information to try to help me solve my problem with my RV.

He reviewed my vehicle and I sent my payment for parts replacement. He never started working on it and decided he no longer wanted to work on my vehicle because the parts money wasn't received on his schedule. Just like everyone else, I work too and was working during that time. read more

He came to my driveway and did a great job installing rear brakes, easy peasy, which was great because we were busy packing up to move. I would definitely use him over and over. read more

Great work and very honest businessman! The problem I hired him for, wasn't the problem I actually had. Instead of completing the work, he stopped before he got too far into the job and told me there were other problems that needed addressing. 10/10 would recommend! David was thorough, informative and knowledgeable. I will use his services again in the future. read more

Lost power center to the camper we live in full time. It got mighty cold. But, David got it all ship shape in no time! He's prompt, responsible, ready to help those in trouble! And he responds to my texts and educates us novices!! Really appreciate him!! read more

I reached out to DNA Services on the 29th (later in the day) and received a response back the next day. I just needed a simple battery replacement for my car. I already had the new battery but needed him to install it. He was very responsive with letting me know when he would be on his way to me and was able to fit me in the same day that I spoke with him. David quoted me a price for the replacement that was very reasonable. When the work was over and I asked how to pay, he stated that God was good to him that day and he was paying it forward and didn't charge me! As someone on a really limited income that meant the world to me (even though I would have happily paid his price as it was already the best price I'd been quoted). I will be back if my car needs future servicing and will also definitely recommend him to everyone I know! Thanks so much again!! read more

David is as honest and real as you can get for a mechanic. I had an issue with my 2011 Altima Hybrid. There was an Exhaust Manifold Leak. Dealership wanted almost $3k to diagnose and fix the leak. They pretty much planned on getting rid of the old and putting in a new one. David diagnosed 2 separate leaks and was able to repair both of them at a considerable cost savings to me, a single parent. David showed me the worn areas and the new ones that he had put in and described the process. Immediately I was able to feel a good acceleration with no hiccups between the electric and gas motor. Engine noise is almost non existent now. This is definitely the guy you need to go to for your vehicle needs. From now on he'll be my go to mechanic. Thanks David! read more

Amazing service! We originally booked David to look at our rv fridge and generator and his service was quick, great price and very professional. Since then we've used only him and he's fixed everything from the fridge to replacing our awnings and fixing our pipes, highly recommend! read more

Wonderful work, fast, honest, good rates, trustworthy. Essentially everything one could ask for in a mechanic. I'll have no question working with them again in the future. read more

DnA is my regular mechanic. I Highly recommend David/DnA Services Paramount!! I will not use anyone else. Reasonable prices and hours. Rain or Shine won't keep them away. I had issues with my 2006 Toyota Rav. The Dealership wanted thousands of dollars to repair and still were not sure of the issue. In time David figured it out and was fixed!! Needed was a complete front/rear suspension, brakes/hub/bearings, shocks, replaced something else? Months later still no issues!! Problem solved!! In addition David has worked on our Camry, 3 of our RV's and 4 x 4. They may be back logged but sure as heck is worth the wait!! Don't give up on him!!! He will always figure out the issue(s), and show up.. In the past I've called other mobile services, they either were back logged, didn't return calls, failed to show, and charged outrageous prices. David truly is an Exceptional Honest Mechanic!! He cares about his Clients!!! I can't ask for a better Mechanic!! read more

I had a issue with my brakes on my RV before we left for camping and it ended up being more serious than just the pads. He ended up fixing it in a couple of days. We will use him again. Thank you Dave. read more

I'm a RV newbie and I had some issues with my water pump and David was a HERO. He went above and beyond my expectations and explained so much to me. This man is a gold nugget!!! Don't go anywhere else. read more

We were trying to sell our RV and the check engine light came on. We called around on the weekend, but this was the only mechanic that was willing and able to work on it. We were added to the list after a long day of other calls and he was able to get us in that day. He was able to figure out the problem and fix it for us! We were very grateful for the quick service and quality work when no one else would do it. He even came to our house to work on it so we didn't even have to go anywhere! This is the second experience and both were fantastic. I am impressed by the professionalism and expertise. I would recommend to anyone! read more

Recently, David came out to diagnose an issue with my car. Long story short - he resolved the problem with my car and saved me a lot of money in return. The thing I really liked about David was his integrity. To find a person like this to diagnose and work on your car is a Godsend. He's genuinely straight talking. I appreciate that, especially, in today's world. I would use him again in a heartbeat and would have no hesitation in recommending him. read more

We were in a sticky situation--stuck in an rv park with worn brake pads that required a 400 meter braking distance in order to stop our 15000 lb RV. David came for a free consultation and was able to start work immediately on our motor home! Amazing job, super recommended! read more

My car had been getting humid inside, to the point of condensation piling up on the inside front windshield. We thought it may have been the heater core that needed replacing. David gave me a super reasonable price estimate to get this done. Upon arriving he decided to check some other things before replacing the heater core. After an hour of checking things he was able to find a leak in the sun roof lining which was the cause of the moisture getting inside the car. Rather than just doing the job agreed on he did his due diligence in checking for other potential issues and saved us a good amount of money. Highly recommended. It's hard to find trust worthy mechanics, so this was a great experience. read more

As good as it gets!! Winnebago RV with V10 Triniton engine suddenly started missing with flashing check engine light. I had no clue where to start, booked an appointment with a regular shop recommended by a friend but their appointments were two months out like most shops these days. Thinking about it did not want to wait until May 31 so searching online stumbled on David's information accompanied by all very positive reviews so I figured what do I have to lose? Left a message via Yelp contact and he replied in a few hours and said he could come to my residence in about four working days which I was elated over. He showed up on time and very efficiently went to work troubleshooting to isolate the source of the misfire. In less than 90 minutes he determined the most likely fault was the #6 spark plug and went to a local parts house to get one. Installed new plug, cleared check engine light then ran Ford diagnostic sequence using his advanced scan tool and everything checked out perfect. We then went for a short test drive to verify that all was well again and my engine was smooth as silk again much to my relief. The total elapsed time was three hours but he only charged me for his normal two-hour minimum plus the cost of the spark plug. I can only say David strikes me as being as honest the day is long and really knows his stuff owing to his rather extensive experience including ten years at a Ford dealership. I will certainly be calling him first the next time my vehicles need help. I told my neighbor about my experience and he is contacting him for help with his RV. I might add that I ran my own auto repair shop many years ago so I was very aware of what he was doing and why and he did not waste any time or steps to quickly resolve my issue. read more
