About Us


Certified Performance is an independent, privately owned auto repair shop and an official NAPA Auto Care Center. As a NAPA Auto Care Center we give you a nationwide 36-month/36,000 mile guarantee on all work we perform. That includes parts and labor. 

At Certified Performance, we work to provide you with personal service. We consider you a valued customer---not just another number in our database and we want you to be pleased with our work so that you will come back again and recommend us to your friends and family.

When we perform any repair on your vehicle, we give your car a complete inspection (front-to-back, top-to-bottom) to check for potential problems, prioritize repairs, and to provide an estimated cost for our services.

All Certified Performance mechanics are A.S.E. certified.  (The National Institute for Automotive Service Excellence in Leesburg, Virginia administers testing and requires hands-on automotive experience before issuing certifications.)
