  • Our History

    Established in 1992, Full Circle Auto Service began at a time when vehicles used carburetors. In fact, our initial incarnation was as a carburetor re-manufacturer and performance shop. After a few years, however, we transitioned from servicing race vehicles to becoming a one-stop shop for the family vehicle. As our services expanded, Carlos aspired to ensure we had the expertise, experience, and equipment to handle any need our customers brought to our door. Once we achieved our training goals in all areas of automotive service, we had come full circle in our commitment to offering complete vehicle repair and service. Thus, our new name was discovered - Full Circle Auto Service!
