Additionally, as a key holder and manager on duty (MOD) when needed, the General Service Technician plays a vital role in providing a superior guest experience, driving sales of automotive services and tires, and ensuring a welcoming in-store atmosphere. Headquartered in our hometown of Rochester, New York, where our founder, Chuck August, opened his first store in 1957, we have grown to nearly 1,300 auto repair shops and tire dealers in 32 states from coast to coast.
