About Martin’s Auto Clinic

Martin’s Auto Clinic is owned by Martin Miller, who works at the shop with his father Art, father-in-law Jay, and long-time friend Bill. We’re all a family of sorts, and that extends to our customers.

Martin’s Auto Clinic was formerly known as Stephen’s Auto Clinic, until Martin purchased it in 2009 from former owner Stephen Nimon upon his retirement. Martin had worked for Stephen in the same shop he now owns since 2004, and he learned a lot from Stephen―not just about cars, but about people, about delivering excellent customer service, and about treating each and every automobile that comes into the shop as if it were his own. Martin has been an auto mechanic since 1993, and is factory trained in servicing Ford, Kia, Mitsubishi, and Toyota. He is an ASE Master Technician, and well equipped to service any make or model vehicle. Martin has always been a part of the Michiana community, having grown up in LaPaz and attended LaVille High School. He earned his degree at Lincoln Technical Institute in Indianapolis in Automotive Service Repair and Management in 1993, and then went on to serve in the US Navy as a Navy Corpsman between 1995 and 2002.

Over the years, Martin has worked on just about every type of automobile there is, both foreign and domestic, and even had the privilege of working on the motor home of Gary Burghoff, who played the character “Radar” in the television hit series, M*A*S*H.

Comprehensive service

As certified mechanics with years of experience, we are accustomed to solving virtually any automotive problem that comes our way. We’re not a big chain that hides its mechanics in the garage. You’ll get to know each and every one of us, and when you come in or call, you can count on talking with someone who truly understands the problem and knows what to do about it.

Locally owned & operated

Your car is more than just a pile of metal you use for transportation, it is part of your identity. You take pride in it, and the car you drive says a lot about who you are. We believe that car repair is a very personal service—or at least, it should be. And for personal service, you need a locally owned and operated shop, and a certified repair person who will take a personal interest in solving your problems and getting you back on the road.
