David Brown



David Brown, General Manager and Technician, has a long history in the automotive service industry. He graduated from elementary school and high school in Weaverville, and went on to attend college at Shasta College and Point Loma Nazarene College in San Diego.   He started working in his Grandfather's service station business while in high school. His mechanical aptitude quickly became apparent and his keen curiosity provided the opportunity to learn over many years while growing up in a family established in the automotive repair industry. Whether 4-wheeling in the snow, off-road, or on the sand dunes, he learned a great deal about gear ratios, tire applications, inflation and safety. David is ASE certified in brakes.

Our Company History

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.  It is great to have David helping in the business! 

Weaverville has been our home since 1982 and our family business of 3 generations is committed to serving the community long-term.
