The Gilbert and Aileen Chuck Charitable Trust is a relatively small but concentrated funder that prioritizes health and medical institutions while also supporting local Ventura County civic services, higher education, and faith‑linked civic causes. Their largest single commitment is to a major cancer/hospital center, supplemented by multi‑sector gifts that include community foundations, legal aid, and faith‑based or civic organizations, indicating a mix of local community focus and selective national or ideological interests.
A single $1.25 million charitable contribution to City of Hope sets the tone for the Gilbert and Aileen Chuck Charitable Trust’s recent giving: large institutional gifts sit alongside a narrower set of community, higher-education, and faith-linked grants. The trust’s 2025 awards also include support for University of Hawaii Foundation, Ventura County Community Foundation, Ventura Co Legal Aid, and St John's Healthcare Foundation, showing a pattern that reaches beyond one issue area while still favoring established organizations. Its mix includes major medical philanthropy, local civic infrastructure, and selected cultural or ideological institutions, rather than broad scattershot giving. The trust appears to work through outright charitable contributions rather than individual aid or program-related investments. The recipient list suggests a preference for organizations with institutional capacity: a cancer and hospital center, a university foundation, a community foundation, and legal aid are all represented among the larger gifts. At the same time, the presence of groups such as Christians Acting Together and Ronald Reagan Presiden Foundation shows that the portfolio is not limited to health or community services. Overall, this is a trust that gives through sizable, targeted grants to a relatively small set of recipients.
Health and medical philanthropy is the clearest thread in the trust’s recent giving. It made a $1.25 million charitable contribution to City of Hope, and also gave $100,000 to St John's Healthcare Foundation. Those two awards point to a strong interest in major healthcare institutions. The trust also supports local civic capacity in Ventura County. It granted $200,000 to Ventura County Community Foundation and $132,000 to Ventura Co Legal Aid, pairing community infrastructure with legal services. A separate $30,000 gift to Christians Acting Together adds a faith-linked civic dimension. Higher education is another visible area. The trust gave $203,600 to University of Hawaii Foundation, which places a university foundation among its larger 2025 awards. Arts or music-related support also appears through a $110,000 grant to Wave Harmony Foundation.

Highly concentrated giving: a small number of relatively large, one‑off grants dominate total giving (one gift accounts for the majority), combining significant single gifts to national institutions with targeted local investments; appears to favor large lump‑sum contributions over many small recurring grants.
Notable grantees: City of Hope, Ventura County Community Foundation, Ventura County Legal Aid, University of Hawaii Foundation, Ronald Reagan Presidential Foundation
Grant sizes are highly skewed: one $1.25 million award stands apart from the rest of the 2025 list, while the next tier clusters at $203,600, $200,000, $132,000, $110,000, $100,000, and $30,000. That spread suggests selective, high-value gifts rather than a broad small-grants strategy. The recent record shows one-year giving rather than a clearly recurring recipient pattern in the supplied data, and the trust’s awards are all listed as charitable contributions. It does not fund individuals and does not make program-related investments. The recipient mix leans toward institutions that can receive larger unrestricted or general charitable support, though the filing language does not specify a formal application process.
All listed recent grants go to U.S. recipients. California receives the largest share of the named awards, including Duarte, Camarillo, Ventura, Oxnard, and Simi Valley. Hawaii also appears twice, through Honolulu and Kihei. The recipient map therefore combines Ventura County-centered giving with selected gifts to organizations outside the trust’s California base, including one award to a Honolulu university foundation.
The recent grants point to health and medical institutions, Ventura County civic infrastructure, higher education, and faith-linked civic organizations. Named recipients include City of Hope, Ventura County Community Foundation, Ventura Co Legal Aid, University of Hawaii Foundation, St John's Healthcare Foundation, and Christians Acting Together.
The 2025 grant list ranges from $30,000 to $1.25 million. The middle of that set is $155,000, with grants of $200,000, $132,000, $110,000, and $100,000 appearing alongside the large healthcare award.
