The Nancy and Geoffrey Stack Family Foundation concentrates its giving on higher education and medical research in Southern California, supplemented by sizable gifts to local community services. They favor large institutional grants to prominent universities (UC San Diego, UC Irvine) and to community-wide intermediaries (United Way), plus targeted disease research funding. Their pattern suggests strategic, high-impact investments rather than many small gifts.
Concentrated, high-dollar grants to a small set of repeat institutional grantees—multiple multi-hundred-thousand to multi-million dollar gifts rather than many small awards; geographically focused on Southern California.
The Nancy and Geoffrey Stack Family Foundation’s giving is anchored by very large general-support grants to UC San Diego Foundation and The Uc Irvine Foundation, signaling a strong commitment to Southern California higher education and the institutions around it. Across the recent grants list, those university gifts sit alongside support for medical research, community intermediaries, and local civic institutions, with general support appearing repeatedly rather than tightly restricted project funding. The foundation’s pattern points to a mix of flagship institutional grants and targeted local giving. UC San Diego Foundation received $1,650,000 in 2025 and $825,000 in 2024, while The Uc Irvine Foundation received $400,000 in each of 2023, 2024, and 2025. That same year-to-year continuity appears in other grants as well, including repeated support for The United Way in Irvine and for Hoag Hospital Foundation in Newport Beach. Beyond the universities, the foundation also backs medical and community-facing organizations such as Cystinosis Research Foundation, Laura's House, Newport Beach Public Library Fd, and Orange County Museum of Art. The overall picture is of a family foundation using flexible support to strengthen large institutions and selected local nonprofits in California.
Higher education is a central theme. The foundation gave $1,650,000 in 2025 to UC San Diego Foundation for general support and $400,000 in each of 2023, 2024, and 2025 to The Uc Irvine Foundation, showing sustained institutional backing rather than one-time project funding. Medical and disease-focused philanthropy is another clear thread. In 2023, Cystinosis Research Foundation received $450,000 for general support, placing rare-disease research within the foundation’s broader university-centered portfolio. The foundation also supports community-serving organizations. The United Way in Irvine received $625,000 in both 2023 and 2025, and Laura's House received $100,000 in 2023, $100,000 in 2024, and $50,000 in 2025. Those grants suggest attention to regional service capacity and local safety-net organizations. Civic and cultural institutions appear as well, including Hoag Hospital Foundation, Newport Beach Public Library Fd, and Orange County Museum of Art, each receiving general-support grants in the recent record.
