ABOUT US
Your local team.
Founded in 1975, A&D—led by founder and President Art Hird—has installed 4,500+ gates across the Bay Area and as far as Arkansas, including at landmarks like the Transamerica Pyramid and Apple Park and for high-profile clients in music, entertainment, and sports. With locations in Redwood City and Tracy, many of our original gates still operate with full integrity. We continue to pioneer new technologies, materials, and methods to remain the Bay Area’s most forward-thinking perimeter security provider.
