Tides Foundation

Back To Partners

Tides is a nonprofit organization that works at the heart of today's most critical issues, supporting grantees and programs that are core to our country’s nonprofit infrastructure and social service delivery. We work in partnership with people whose work confronts issues like global warming, AIDS treatment and prevention, and economic disparity. Bringing together people, resources, and innovation, Tides is a convener and connector for those in our community and beyond. 

We provide fiscal sponsorship for over 230 groups across the country, operate and support green nonprofit centers, and grant millions each year to charitable organizations across the globe. Issues we support include a veterans re-entry program, the improvement of community clinics in California, people in Africa receiving treatment for HIV, arts programs for inner city youth, adolescent nutrition, ending violence against women, civic participation to make our democracy work, and much more.

With offices in San Francisco and New York City, Tides is a network of organizations made up of Tides Center, Tides Foundation, and Tides Shared Spaces.
