SMALL TOWN ROOTS, BIG DREAMS

We launched Doc’s Diesel in 2020 with a simple mission: Make Diesel Maintenance Easy. When it was time to service our truck’s, we were sick of the dealership charging us an arm & a leg. Then when we decided to do-it-ourselves, it was hard to find all the filters our truck needed in one place online. Usually they were out of stock or we couldn't trust a cheap amazon brand. That's when we decided to spec and design filters that meet or exceeded OEM standards while cutting out the middleman.


It all started with a little inspiration from my Grandpa Doc...

Grandpa Doc was the one who changed the trajectory of our family with his entrepreneurial spirit. He paved the way for bigger ideas, bigger vision, and bigger execution. He exemplified hard work and a love for his people. Early on, he owned farmland, then went into the dump truck business, then owned a Ford Dealer, and ultimately got into the auto parts business, where he really dug deep. He passed away when I was a kid, however, I’m thankful for the time we had together. I started this business with his spirit in mind. I wanted to bring some of his principles into the 21st century and continue his legacy, thus, starting Doc’s Diesel. It makes me happy seeing all of the great reviews and happy customers, knowing how proud this would have made Grandpa Doc.
