Our History


Madison Auto Trim is started by owner Ron Stevens. Ron is a one man show for years! He would stock his van with all the accessories and tools to provide door-to-door service for area dealerships. Ron would sell and install everything from pin-striping to spoilers to more than 10.000 sunroofs!


The First retail location opens a few blocks off the capitol on East Washington Avenue. It's located within the parking lot of the Don Miller Downtown dealership location. Madison Auto Trim takes over all the detailing services for all the Don Miller locations. MAT offers retail detailing and accessories as well.


Don Miller opens a new West side location and Chad Stevens becomes General Manager of all detailing.


Madison Auto Trim moves into its current 18,000 square foot location on the east side of Madison off High Crossing Blvd, Tim Stevens becomes General Manager of the East location. Services expand and M.A.T. starts offering body repair and painting, many vehicle accessories, and now has a retail showroom
