The Maurice and Joanna Sullivan Family Foundation concentrates its giving in Hawai‘i, making large, unrestricted gifts primarily to private K–12 schools and local health providers. Their grants favor established Honolulu institutions — both elite independent schools and major hospital/health systems — while also supporting local higher education and community food systems. Giving appears locally focused and mission-flexible, with funds often used as general operating support.
Relatively concentrated, high-dollar, unrestricted grants to a small number of local institutions; mix of repeat support for core grantees (notably Iolani and Blood Bank of Hawaii) and single large gifts to major Honolulu organizations.
Maurice and Joanna Sullivan Family Foundation’s recent giving is marked by repeated unrestricted grants of $300,000 and $250,000 to Honolulu institutions, with private schools, health systems, and community-serving nonprofits appearing again and again. The foundation’s largest recent awards went to Queen's Medical Center, Iolani School, Punahou School, and Charminade University, showing a pattern of substantial general support rather than project-specific funding. That same approach extends to Hawai‘i-based medical and civic organizations such as The Queen's Health Systems, Blood Bank of Hawaii, and Kapiolani Health Foundation, which also appear among the larger gifts. The grant list suggests a funder that backs established local organizations with flexible dollars, especially where those groups provide education, healthcare, and essential community services. Smaller but still sizable grants to Ma'o Organic Farms and the Honolulu Museum of Art show that the foundation also supports food systems and cultural institutions in the same unrestricted style. Across the recent record, the common thread is sizable core funding for organizations embedded in Honolulu and broader Hawai‘i civic life.
In education, the foundation supported several Honolulu schools and universities with unrestricted gifts, including $300,000 to Iolani School, $300,000 to Punahou School, and $200,000 to Charminade University. The health portfolio is similarly clear: it gave $270,400 to The Queen's Health Systems, $200,000 to Kapiolani Health Foundation, and $150,000 to St Francis Health System of Hawaii, all as unrestricted gifts. Community infrastructure also appears in the giving record. Blood Bank of Hawaii received $250,000 in 2024 and another $250,000 in 2025, while REHAB Foundation received $100,000 in both 2024 and 2025. The foundation also made unrestricted gifts to Ma'o Organic Farms and Kupu Hawaii Foundation, linking its support to local agriculture and environmental or youth-related work.
Typical grant size is $75,000 at the 25th percentile, $100,000 at the median, and $150,000 at the 75th percentile, with many recent awards above that range. The foundation’s giving is heavily recurring: several recipients appear in multiple years, including Iolani School, Punahou School, Charminade University, Kapiolani Health Foundation, Blood Bank of Hawaii, and REHAB Foundation. The grant records show a family foundation making flexible support decisions, and the prevailing grant type is unrestricted gift. No application process is described in the data.

Notable grantees: Iolani School, Blood Bank of Hawaii, Punahou School, Queen's Medical Center, Ma'o Organic Farms
The foundation gives locally, with 98% of grants going to recipients in Hawai‘i. Honolulu dominates the recipient map, and Waianae also appears among the recent awards through Ma'o Organic Farms. The country distribution is entirely U.S.-based, with 72 grants in the United States and no non-U.S. recipients in the dataset. That pattern shows a concentrated Hawai‘i grant portfolio rather than a multi-state or international one.
