The Sam Mazza Foundation

What The Sam Mazza Foundation does

The Sam Mazza Foundation is a private 501(c)(3) nonprofit charitable foundation established in 2005 from the estate of Sam Mazza, a San Francisco painting and interior decorating contractor who in 1959 purchased the historic Mazza Castle in Pacifica, California for approximately $29,000. Following Mazza's death in 2002 at age 96, his estate was converted into the foundation, and the board of directors elected in 2005 to retain the century-old castle (built in 1908) as both the foundation's headquarters and an operational cultural venue.

The foundation's core activity is grantmaking to Bay Area nonprofit performing arts and arts education organizations, including past support for Cal Performances/UC Berkeley (bringing Alvin Ailey American Dance Theater to the region), Dance Mission's GRRRL Brigade, Spindrift School of Performing Arts, Music at Kohl Mansion, Ars Minerva, Comedy Day, SFJAZZ, and Look What She Did. Grants are directed at funding programming, performance opportunities, and arts education initiatives across dance, music, theater, jazz, comedy, and short film.

Operationally, the foundation runs Mazza Castle as a public cultural venue, offering guided castle tours, a continuing Castle Music Salons concert series featuring Bay Area and international musicians, and themed special events including holiday teas, Mother's Day services, Halloween galas, and author readings. The organization is governed by a small board of directors and operates with a 5-person staff; it files as a private foundation on Form 990-PF, does not sell products, and offers public programming free of charge or for modest fees. There is no disclosed revenue, no commercial pricing model, and no parent company.
