A Legacy of Expertise in Subaru Engine Machining

in Kent, WA

Founded by Mark Bryant, widely known as "Independent Subaru Guru," East Valley Auto Rebuild was formally established in 2003 in Kent, Washington.


Mark and his wife Denise Bryant have built a family-owned business rooted in integrity, skill, and the simple belief that "our clients are our biggest asset."


Mark's journey began at Aaron's Auto Wrecking, a Subaru-only yard, before co-founding Brian's Subaru Clinic. Over the decades, his experience has evolved from small-scale repairs to building one of the most respected Subaru machine shops in the Pacific Northwest.


Now operating out of a 7,000-square-foot facility at 22647 88th Ave South in Kent, East Valley Auto Rebuild continues to serve Seattle, Tacoma, Auburn, Renton, Federal Way, and beyond.



Our company philosophy, "A Journey of Gratitude and Growth," reflects how we approach every project—with thankfulness, dedication, and the drive to continually improve.
