Dennis Cooper started repairing cars from a simple one-door garage with two bays. Over the last 30 years, his needs have steadily grown, as his robust business repeatedly outgrew four- and six-bay facilities. He and his team of ASE-certified technicians now stretch their legs through eight service bays, with Dennis's wife, Kathy, keeping watching over the books. Experienced technicians—including two ASE master mechanics—perform maintenance and diagnostic services on every part of vehicles and frequently add to their knowledge with seminars and schooling.

The center boasts a Hoffman wheel alignment system, which uses a Windows operating system and multiple laser beams to ensure accurate alignment, as well as two oversized shop bays to accommodate larger and diesel vehicles. The Cooper's Automotive team can also soup up performance with off-road lift systems or give vehicles a distinctive look with a custom fixtures and chrome tips. Recognized for excellence in emissions repair, the shop also recently installed solar panels on its roof to produce electricity and reduce its carbon footprint.

Cars are made to travel. But after a long trip overseas and miles of maneuvering American roads, import vehicles still require their own brand of service. That's where Automotive Specialists comes in. Specializing in Japanese imports, the shop's ASE-certified technicians reboot cars by repairing transmissions, alternators, and electrical systems. Maintenance services such as oil changes and tire rotations breathe new life into vehicles that have been slowed down by sluggish engines or ticklish tire treads.
