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.
