About Us

About Car Smart Auto Service!

Family-owned since 2006

We are a family-owned business that has been serving our customers since 2006. Jeffrey and Kristi Grassman purchased a recently closed business in the Auburn area, relying on Jeffrey’s background as a technician and his entrepreneurial spirit, they revitalized the company with a mission to provide quality auto repairs and service at a competitive price. In 2013, the business relocated to Sumner, WA where the Car Smart brand has become a trusted auto repair shop of choice.

Our family places a high value on providing employment opportunities for team members that will help them thrive and achieve their dreams. Our interest is to see employees and their families be successful and we want to partner with them to get there.

Our passion is to help people get to their destination. Thank you for trusting us to help you get to yours.
