Tides accelerates the pace of social change, working with innovative partners to solve society's toughest problems.

Tides actively promotes change toward a healthy society, one which is founded on principles of social justice, broadly shared economic opportunity, a robust democratic process, and sustainable environmental practices. Tides believes healthy societies rely fundamentally on respect for human rights, the vitality of communities, and a celebration of diversity.

Tides is a nonprofit organization that works at the heart of today's most critical issues, supporting grantees and programs that are core to the country’s nonprofit infrastructure and social service delivery. The organization works 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 the community and beyond.

Tides 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 Tides 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 the 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.
