02 / OUR STORY

DIESEL RUNS
IN THE FAMILY.

David Martinez learned the trade in his family's fuel injection rebuild shop in Peru, working on injection pumps and injectors.

After moving to the U.S. in 1999, he spent years at Tyner's Truck Repair in Athens under the well-known Larry Tyner, who became a big mentor to him. He went on to Diesel Fuel Systems in Lawrenceville, where he kept building his love for fuel injection shop work.

In 2013, David opened Oconee Diesel Center in a small warehouse in Lawrenceville. The shop has grown ever since, and we've called Statham home since 2018. We're proud to be a known name serving fleets, owner-operators and diesel equipment owners across North Georgia.
