Very personable...knew what he was doing, confinatelly...found other problems, and fixed them...All I had to offer was a carport, and it rained incessantly, with no complaints. I would recommend Jason to ALL my friends. He actually fixed more than I expected and saved me beaucoup dollars over my usual Shop.

Did a great job on my Honda

Jason can do the work very quick. The knowledge he has as a mechanic is very insightful. It's good to know what cars use in their technologies and Jason will tell you what's happening. He cares about the service being worked on and I would recommend most customers to give him a call with YourMechanic. He noticed a crack in my reservoir when I bought a used car. I had some JB weld and he put on a couple coats after using a tool to find the damage. Nobody wants to run into an extra problem like that. So that's a real good guy. Thanks!

Jason was excellent and very informative. He arrived on time had a discussion on the issue of the vehicle and he said no problem and took over from there. He was done in no time and even went out of his way to alert to me of future maintenance items I should keep an eye on that he noticed while working. I will definitely request him again for future work.

Jason is very friendly, efficient and knowledgeable. He was prompt, (even a few minutes early). After replacing my starter, showed me exactly what was wrong with the old one. I asked about a couple more service jobs I wanted to consider. He explained them and sent quotes. Excellent service! I would like Jason back for future work.

My second time with Jason. Same high level of service. Very conscientious. Doesn't just "work on your car" but has researched you problem and offers thoughtful opinions and options. I'm pleased to have found a trusted mechanic paired with a brilliant, convenient service! I'll be asking for him again for future needs. And now my wife wants to begin using this service for maintenance on her car as well.

Very nice and professional. Blew my mind. As the old military saying: went beyond his call of duty. Can definitely be trusted

Booked an appointment with Jason for my wife’s car since it was running rough at idle. I thought I needed new spark plugs and was quoted $372 for the job, which I agreed to. After inspecting the car Jason informed us the the plugs were good but the problem was a bad PVC hose or sensor. To make a long story short, the price was reduced to $132 since we only paid for the diagnostic and parts. Was very pleasantly surprised and happy at the amount of money we saved from not having unnecessary repairs done. Would highly recommend Jason to anyone needing work done on their vehicle. He’s honest, friendly and very knowledgeable.

I was pleasantly satisfied with Your Mechanic;Jason was professional, courteous, knowledgeable and articulate. Jason took the time to explain the process about the repair, what his analysis found and suggested course of action. The original recommended repair was found to be unnecessary but substituted with a less expensive repair. The safety inspection uncovered another area of concern for future consideration in the near future. Overall, we are satisfied and will consider Your Mechanic again. Thank you
