Our Mission

The Spinsters of San Francisco (SOSF) is a social and philanthropic organization of young professional unmarried women unique to the San Francisco Bay Area. Since 1929, SOSF has created a strong network of women who make a positive impact in the community through volunteering and fundraising events.



The Board of Directors of Spinsters of San Francisco acts as the executive leadership team, overseeing all events, activities, and interactions of the organization between our chosen non-profit partner and the San Francisco community.
