The Harry L. Willett Foundation concentrates its giving on a small set of sizable grants that support medical research and clinical programs—particularly cardiovascular work—and place-based environmental conservation. It shows a mix of local/regional investments (watershed protection in Wimberley) and targeted biomedical research funding (named research gifts to university health systems), with a smaller strand of international medical training/education support.
Harry L Willett Foundation C O Boyd Ryan’s largest recent grants point to a clear split between medical training and place-based health work. In 2024, it gave $600,000 to Earth Mission - Asia for the Jungle School of Medicine, and in the same year it directed $575,000 to Seton Hays Foundation for general program support. That pattern continues across multiple years: the foundation has returned to Seton Hays Foundation repeatedly for cardiovascular and county-level care, while also backing named biomedical research through university health systems. The foundation’s recent grant history shows a preference for sizable awards rather than many small gifts. It supports patient-facing programs, clinical departments, and research efforts alongside environmental and community projects. Alongside medical work, it has funded watershed protection and local conservation through the Wimberley Valley Watershed Association, and it has also made grants tied to rural education and international medical training. Its portfolio includes both unrestricted support and purpose-specific gifts, with several beneficiaries appearing more than once across the recent grant list.
Cardiovascular care is one of the foundation’s clearest priorities. It gave $500,000 in 2023 to Seton Hays Foundation for cardiovascular programs and another $500,000 in 2023 for the Kyle cardiology department, then followed with $500,000 in 2025 for Seton Hays County and $100,000 in 2025 for the Childrens Care-A-Van. Biomedical research is another recurring thread. In Tyler, it awarded $350,000 in 2024 and again $350,000 in 2025 to Uthsct Office of Institutional Advancement for Dr Tilley research, and in 2023 it gave $350,000 to Hthsct Office of Institutional Advancement for Dr Philley research. The foundation also backs conservation and community projects. It made grants to Wimberley Valley Watershed Association in 2024 and 2025 for general support and Art4Water projects in San Marcos, and it supported the Wimberley Valley Watershed Association with $320,000 in 2023 for general support.
Typical grant size sits at $10,000 at the 25th percentile, $27,000 at the median, and $65,000 at the 75th percentile, though the recent list includes several much larger awards. The grant record shows repeated support to the same organizations across multiple years, including Seton Hays Foundation, Wimberley Valley Watershed Association, Earth Mission - Asia, and Uthsct Office of Institutional Advancement. The foundation makes program-related investments and funds individuals is false. Its giving appears to be grant-based rather than application-driven, since no application process is shown in the data.

The grant record is national, with all recent listed grants going to U.S. recipients. Montana appears most often by grant count, even though Colorado is the headquarters state and receives 8% of grants. Recent awards cluster in Texas cities such as Kyle, Wimberley, Tyler, San Marcos, Austin, and College Station, while other recipient locations include Siloam Springs, Arkansas; Billings, Montana; Newark, New Jersey; Columbus, Ohio; and Denver, Colorado.
Its recent grants center on cardiovascular care, biomedical research, watershed and conservation work, international medical training, and selected community projects such as school additions, adaptive sports, and women’s services. The largest recurring medical relationships are with Seton Hays Foundation and university health-system research offices.
Yes. Several recipients appear across multiple years, including Seton Hays Foundation, Wimberley Valley Watershed Association, Earth Mission - Asia, and Uthsct Office of Institutional Advancement. That suggests an ongoing relationship style rather than mostly one-time gifts.
The typical grant size is $10,000 at the 25th percentile, $27,000 at the median, and $65,000 at the 75th percentile. The recent record also includes much larger awards, including $600,000 to Earth Mission - Asia and $575,000 to Seton Hays Foundation.

Yes. The foundation is listed as making program-related investments. It also does not fund individuals, so its support is directed to organizations and institutional programs rather than personal awards.
