Brad Vacketta: Brad started the company in 1979 when he came to Columbus to try out his new mechanical engineering degree with Cummins. Having the desire to run an automotive service shop full time led him to resign from Cummins in 1984 and be his own boss …and be his own bookkeeper, receptionist, and janitor. He is married to Lorraine and has two children.

He sees the business as an opportunity to grow, serve others, and give back to the community. Brad’s faith in God motivates him to be honest, respectful, kind, and fair.
