Our Story
Diesel Truck Repair was built on a passion for trucks and a deep understanding of what it takes to keep them running. Our owner, Michael Shepherd, started his career at just 17, working in dealership service bays and honing his skills in aftermarket truck repairs and parts sales. Over the years, his experience expanded to working as a school bus mechanic while steadily growing the business on the side. With each turn of the wrench, Michael’s vision remained the same—focus on diagnosing and fixing the root cause of problems instead of just replacing parts. That honest, no-nonsense approach is what drives our shop today.
From our humble beginnings to a full-service shop with eight bays and two mobile service units, we’ve grown with one goal in mind: to provide reliable, honest service that keeps our customers moving. Whether you’re an independent owner-operator or managing a fleet, we treat every truck like it’s our own and every customer like family.

Went to the dealership, they wanted a mortgage on the part, started shopping online was skeptical. Pull the trigger on the actuator and had to dealership put the part on and calibrate it. Smiling from ear to ear
Really great service. I came in with a engine debate problem and they stayed late to get it fixed. Tanner explained everything and didn't make me feel slow. He talked and he also listened. I really wish more mechanics in this industry did that. The prices were not crazy. Real people doing a real job and treating others like real people. I'll definitely be back for service when I'm in the area.

Top notch service from these folks! Had one of our trucks break down on New Years Day of all days.. Called Michael and he was ready to go at a moments notice. Got out there and fixed our issues quickly and got us going asap! Great company, reasonable prices, honest work!
Fast and friendly service.
Great part at a more than fair price. This place is my first call every time I need something from here on out. Thanks again!!!
These guys really know there mechanic work. I needed a starter on my Freightliner and they got it done even though it was after business hours. Mike and Chris truly are the mechanics you would want to work on your truck. Appreciate you guys.
Fantastic! Had a brake chamber bust loose mid afternoon on a Saturday and was assuming it would be LATE getting it fixed, if not having to wait til Monday. These guys gave my breakdown desk a pretty exact ETA, then also called me directly when they started my way, and showed up exactly when they said. Quick diagnosis, then they picked up the new can and met me back at their new, easy, convenient yard. Quick work, very reasonable, great guys to talk with. They are eager, knowledgable, and seem to be very focused on good, honest service. The shop we all wish we could find when we're no where near the house!
Top notch!! These are great people to do business with. Reliable and on time. I'll be a repeat customer. Thanks
My truck was packed for 2 months, when I started to go back to work, I was putting a lot of antifreeze, that antifreeze was coming under my transmission and it was mixing oil and antifreeze, Chris told me the transmission cooler is bad, and he fixed the problem, he is really good mechanic, from now on I will take my track over there if I need anything, Chris and Mike they are friendly, and they do the job well, I recommend my fallow truckers, to check over there, thanks Chris and Mike 🙏
