About Duffy Foundation
The Duffy Foundation concentrates its philanthropy locally in Ann Arbor with very large, repeat gifts to a small number of organizations. The foundation’s giving is heavily weighted toward a single education/retiree-focused beneficiary (UMRC Foundation) and a sizable commitment to service-animal training (Paws With A Cause), indicating priorities in elder/retiree community support and assistance-dog programs.

About Duffy Foundation
A single relationship stands out in Duffy Foundation’s recent grant history: a $10,849,173 grant to Umrc Foundation in 2025, followed by additional support in 2024 and 2023. That pattern signals a funder that uses large, repeated awards rather than broad, scattered check-writing. The foundation’s recent giving also includes three consecutive $650,000 grants to Paws With a Cause, showing another sustained commitment over multiple years. Duffy Foundation’s grantmaking is tightly centered on Michigan nonprofits, with most recipients in Ann Arbor, Chelsea, Howell, Ypsilanti, and Detroit. Its portfolio includes organizations tied to retiree services, assistance-dog training, housing stability, food access, medical care, and local civic institutions. The grants suggest a preference for established public charities that can absorb substantial operating support or major project funding. The pattern is highly concentrated in a small set of organizations. Alongside its largest recipient, the foundation has supported Shelter Association of Washtenaw County, St Louis Center for Exceptional Children, Food Gatherers, and the Ann Arbor Area Community Foundation with repeated awards across recent years.
What Duffy Foundation Funds
Duffy Foundation gives across a small set of local service areas, but the strongest pattern is support for retiree and community-service institutions. In 2025, it awarded $300,000 to St Louis Center for Exceptional Children - General Operating, and in prior years it gave $275,000 in 2024 and $275,000 in 2023 to the same organization. Housing and homelessness also appear in the record. The foundation gave $400,000 in 2025 to Shelter Association of Washtenaw County, after earlier grants of $275,000 in 2024 and $275,000 in 2023. Basic needs are another recurring theme. Food Gatherers received $300,000 in 2025, $250,000 in 2024, and $220,000 in 2023, while Hope Medical Clinic Inc received $220,000 in 2025 after $210,000 grants in both 2024 and 2023. The foundation also backed community infrastructure with a $200,000 grant in 2025 to Ann Arbor Hands-on Museum.
How Duffy Foundation Gives
Duffy Foundation’s typical grant size sits at a p25 of $42,500, a median of $80,000, and a p75 of $155,000, though its recent awards include much larger outliers. The repeated grants in the recent record point to multi-year relationships rather than one-time gifts. Its portfolio also shows a strong preference for U.S. 501(c)(3) public charities, with compliance and eligibility screening built into the funding model. The foundation does not fund individuals and does not make program-related investments.
