Cornerstone Auto & Tire Center is proud to continue a family tradition of service to Trinity County residents and visitors.  Luke & Bobbie Lucas moved to Weaverville in 1982 along with their son-in-law and daughter, Larry & Nancy Brown (and their 2 children, David & Jeanette) when Luke purchased Trinity Chevron.  Since that time, the service station evolved to Lucas BP, then Lucas 76, which was sold in 2004.  Lucas Tire & Automotive was an offshoot of the service station in 1990, and when Luke retired in 2004 and closed Lucas Tire & Auto, Larry & Nancy continued the family tradition by opening Cornerstone Auto & Tire Center at the same location.  We have been privileged to raise our children here and be a part of this beautiful, small, supportive mountain community.  

David Brown is the third generation now working in the shop and is currently the General Manager.

Weaverville has been our home since 1982 and three generations have been committed to serving the community long-term.
