About Us DJ'S Repair Service, auto repair shop in Chamois MO

Linn and Osage County's Go-To
Auto Repair Shop

DJ's Repair Service was born out of a genuine need in Osage County for reliable, quality auto repair. As an ASE Certified Master Tech, DJ Keilholz had the skill and knowledge to fix cars, and his family, friends, and neighbors had vehicles they wanted him to work on. By opening his own auto repair shop, DJ simply made it official—he's the go-to guy in Osage County for Missouri State Inspections, alignments, batteries, oil changes, brakes, general repairs, and more!

In 1997, DJ started working for Jerry Baker at Jerry's Repair Service in Chamois, and then attended State Technical College of Missouri (formerly Linn Tech) after graduating from high school. He received his certificate in Automotive Technology in May of 2000. Even before he received his certificate, DJ had started working at a dealership, and he became ASE Master Certified.

Shortly after leaving the dealership, DJ started working at an independent auto repair shop in Jefferson City, MO, and on nights and weekends, he assisted family and friends with their vehicles. When he realized Osage County needed a reliable local repair shop, DJ along with his wife, Dawna, decided to open his own business to help the community.
