In Illinois you have to be licensed to unclog a drain or cut someone’s hair, but not to work on an automobile. ASE (the National Institute for Automotive Service Excellence) gives you the confidence you deserve when selecting who services your vehicle. At Johnson’s Automotive Service, you never have to worry because all of our technicians are certified by ASE, and over 70% of them are ASE certified Master Technicians. This voluntary accreditation is just another way we display our dedication to our industry and our customers.
