Salter consults on over 900 worldwide projects each year with headquarters in San Francisco and branch offices in San Jose, Los Angeles, Honolulu, and Seattle. In 1975, Charles Salter founded the company on principles of sound engineering, scientific process, inquisitive problem solving, and personal integrity. His motto was simple: to be better every day. Having grown from 1 engineer to a team of 50 that includes acoustical, audiovisual, telecommunications, and security experts, that commitment remains the same.
