What The San Diego Foundation does

The San Diego Foundation is a 501(c)(3) community foundation founded in 1975 and headquartered in San Diego, California. It serves as the only regional community foundation in San Diego County, connecting individual donors, families, nonprofit organizations, corporate partners, and professional advisors (wealth advisors, estate planners, tax planners) with charitable giving vehicles and grantmaking. Core products are donor-advised funds (DAFs) and a suite of specialized fund types including Legacy, Scholarship, Corporate, Field of Interest, Nonprofit, Mitigation, Designated, and Discretionary Funds, with minimum opening balances of $25,000 for individuals and $50,000 for nonprofit agency funds. Supporting programs include the $500M Fifty & Forward campaign, the crisis-response San Diego Unity Fund, the monthly San Diego Impact Circle starting at $10/month, and the San Diego Housing Fund with a goal of 10,000 new units by 2034.

The foundation's technology stack centers on the MySDF donor portal for fund management and online grant recommendations, alongside a professional investment management system running seven investment portfolios (endowment and non-endowment variants) overseen by an Investment Committee. Five wholly owned supporting organizations (Coastal Community Foundation, San Diego Housing Fund, San Diego Women's Foundation, Charitable Real Estate Foundation, and Policy & Innovation Center) extend the operational surface; PIC is a joint venture with the County of San Diego and Brookings Institution for regional research and policy analysis.

The business model is nonprofit: revenue is generated primarily through administrative fees on charitable funds (reinvested into grantmaking, programs, and operations) and investment management, while charitable contributions from donors — accepted as cash, securities, real estate, and complex assets — flow through to grants. As of the most recent disclosures, SDF manages $1.6 billion in assets across 2,400+ charitable funds, has granted more than $2 billion since 1975, and deployed a record $150 million in grants in its most recent fiscal year under President and CEO Mark A. Stuart. Distribution combines a direct Donor Services team, professional advisor partnerships, six regional affiliates (Carlsbad, Chula Vista, Escondido, Oceanside, Ramona, Rancho Bernardo), the annual San Diego Fundraising Conference, and digital channels.
