Keeping You On The Road For Two Generations

After 20 years in the US Air Force, Darell Hertenstein Sr. started DH Automotive in a two-car repair shop in St. Marys, OH. Within five years, the business grew to a four-bay workshop. Darell worked mostly by himself until his son, Ted Hertenstein Sr., joined him in the spring of 1988. Before beginning his career at our shop, Ted served in the US Air Force for four years. Darell and Ted were soon joined by Michael Hertenstein, who also served in the US Air Force. Before starting at DH Automotive, Michael worked at Crown Equipment.

In 1990, we moved to our current located on South Wayne Street in St. Marys. In 1993, after 20 years in the automotive repair business, Darell felt the need to retire. He was confident the business would be in good hands with his sons. On February 29, 1994, Mike and Ted Hertenstein became the sole owners of DH Automotive. After 25+ years as owners of DH Automotive, Mike and Ted still hold true to the values their father taught them: listen to the customer, be honest, trustworthy, and professional.
