About Us

Auto Repair shopWelcome to our website. My name is David Cornelsen. I am the owner of CORNELSEN AUTOMOTIVE REPAIR SERVICE, which has been in operation in Amarillo for eight years now. We are a Tech-Net Professional shop that employs only ASE certified techs.

Growing up I had a passion for fixing things and learning how things worked, especially cars. After graduating high school, I attended Oklahoma State Tech in Okmulgee, Oklahoma, where I received my Associates Degree in Auto Mechanics . In May of 2003 , Cornelsen Automotive Repair emerged open for business.

We are a family owned and operated business. My son John is our lead Technician. We attend classes and seminars throughout the year to keep up with the ever changing automotive industry. Together , we have over 45 years of experience in the auto industry, and we offer a complete line of service for your vehicle.

No one enjoys a car repair or breakdown. Allow us the opportunity to serve you. We will explain the service needed, give you an estimate and put you back in your vehicle as soon as possible. Fast friendly service done with honesty and integrity is our goal.

We have recently moved to a larger shop to facilitate faster service; with 6 bays, three lifts and updated tire equipment to better serve our customers. Let us put our high standard of service to work for you.
