We bring the same dedication to all of our clients—those who have already arrived and those who are on their way or just getting started.

Richard J. Sideman and David P. Bancroft left distinguished careers as assistant U.S. attorneys to found the firm in San Francisco in 1978. They are believed to be the first former federal prosecutors in Northern California to open their own firm. They brought deep expertise in tax controversy and criminal defense matters, which remain cornerstone practices in the firm today. More than four decades later, Sideman & Bancroft has grown to nearly 40 attorneys across twelve niche practice groups. Our firm’s reputation as a premier boutique in the United States is well deserved.
