Washington’s Trusted Source for Service Since 2012

The Story of Peterson Automotive and Diesel

Brad Peterson founded Peterson Automotive and Diesel in the fall of 2012, built on a vision of honest and reliable car care and a deep commitment to serving the local community. In April 2025, Brad sadly passed away, leaving a strong legacy we are deeply honored to continue. Derek Widmer, who worked alongside Brad since 2013, and Gabby Braves have since taken over. They are committed to upholding the quality, integrity, and community-first approach that made this shop what it is today. We are eager to carry on Brad’s vision while continuing to grow and serve our customers with the same passion and commitment. We are excited about the future and appreciate the chance to keep Peterson Automotive and Diesel moving forward, fueled by the support of customers like you.
