Our story starts back in 1985 when Robert "Bob" Baum and his wife Donna purchased the store that would become Baum's Auto Supply. Their goal was to establish an auto supply store that would provide the community with merchandise in a personal and friendly atmosphere.  The tradition remains the same to this day, all our employees share a positive attitude and work hard for every customer to ensure a great experience.

Here at Baum's we provide a wide range of parts and supplies for foreign and domestic vehicles. Brakes, cooling, engine internals, filters, fuel and air delivery, ignition, steering, suspension, car care products and accessories are readily available seven days a week. From Acura to Volvo, we've got you covered!
