    About Us

    Past

    With over 46 years experience in Porsche service and repair, Ralph Simmers began his automotive career with Porsche at the age of 21 with Stuttgart Import Corporation in Towson, MD. Stuttgart Import was one of the first Porsche dealers in the country. Ralph was fortunate to crew as mechanic for various race teams, including Bruce “King Carrera” Jennings and the fabled Toad Hall Racing during the 1969, 1970 and 1971 campaigns at Sebring and Daytona.

    Ralph’s Auto Service opened as an independent Porsche shop in 1971. We take pride in servicing everything Porsche, including the earliest 356 models, Speedsters, 356 A/B/C/SC, 912, 911, 911 Turbo, 914, 914-6, 924, 944, 944 Turbo, 968, 964, 993, 996, 997, 991, Carrera GT, 918, Boxsters, Caymans, Panameras and Cayennes. Ralph’s has a certified Porsche Gold Master Technician on staff to supervise and oversee critical jobs. Your Porsche will be serviced using OEM parts whenever possible.

    We also provide detailed preparation for vintage rallies, track days, and competition motorsports. We have grown over the years through hard work, courteous service, honesty and impeccable quality that only five decades of experience can deliver.
