About Us:
The Story Behind DMR Diesel Repair

DMR Diesel Repair wasn’t just built—it was earned through years of dedication, hard work, and a deep passion for diesel trucks. Dylan Reynolds has been around diesel engines since he was eight years old. While most kids spent summers on vacation, Dylan spent his time in the shop, getting hands-on experience and learning the trade from the ground up.

The early days weren’t easy. Dylan started out renting space in a cabinet shop’s parking lot, working on trucks in less-than-ideal conditions. When that space fell through, he moved to a dirt lot, pulling transmissions on plywood. Over time, with relentless dedication, he saved enough to pour a concrete slab, install a lift, and finally move into his current shop in August 2023. From working under a pop-up canopy in the Florida heat to running a full-service diesel repair shop, Dylan built DMR Diesel Repair from the ground up—literally.
