From Commercial Artistry, to a leader in Design-Build


For six decades, WeidnerCA has consistently enhanced our client’s vision. It started in 1955 when an entrepreneurial police officer started hand-painting signs to earn extra money. Since then, WeidnerCA has grown to become a trusted partner for some of California’s most noteworthy developers, contractors, and companies across the West Coast.
