The Potamkin Family Foundation makes a small number of sizable, unrestricted grants primarily to South Florida institutions, with an emphasis on local child- and family-serving organizations, medical and neurological research/hospitals, cultural institutions, and animal welfare programs. Their giving favors general operating support to established nonprofits in Miami–Dade County rather than many small or project-specific awards.
A large share of Potamkin Family Foundation Inc’s recent giving is centered on Miami-based child and family services, led by a $105,565 grant to Kristi House for general operations. The foundation pairs that work with support for local animal welfare, medical institutions, and cultural organizations, using a pattern of sizable unrestricted awards rather than many small project grants. In the latest grants list, a $100,000 award to Miami Dade County General Operating funded stipends for cat spay/neuters under the direction of Street Cat Clinic, Inc., showing that the foundation also backs direct animal-population management in Miami-Dade County. Other recent grants include $85,000 to Mount Sinai Medical Center Foundation for general operations and $60,000 to American Brain Foundation for general operations, indicating that health and research remain part of the mix. The recipient list also includes Miami-based arts and youth institutions, which places the foundation’s giving across several local civic sectors while keeping most awards concentrated in South Florida.
Child protection and family services appear as a clear theme in the recent record. Kristi House received $105,565 for general operations, and Mujeres Unidas en Justicia Educacion received $25,000 for general operations. Health-related giving includes $85,000 to Mount Sinai Medical Center Foundation and $60,000 to American Brain Foundation, both unrestricted awards. The foundation also supports community institutions for children and culture: Miami Childrens Museum Inc received $50,000 in 2025 and $7,500 in 2024, while Perez Art Museum Miami received $50,000 for general operations. Animal welfare is another recurring area, with $12,883 to Humane Society of Greater Miami and $5,000 to Miami Veterinary Foundation, alongside the cat spay/neuter funding routed through Miami Dade County General Operating.
Typical grants cluster at a meaningful size: the p25, median, and p75 are $25,000, $25,000, and $60,000. The recent record shows a small number of larger awards alongside a few lower-dollar grants, including a $1,000 award in 2025. Several recipients appear more than once across the listed years, such as Miami Childrens Museum Inc, which received both $50,000 and $7,500. The pattern is strongly oriented toward general operations and unrestricted support, with one direct-service exception for cat spay/neuter stipends. The foundation is a private family foundation and does not fund individuals or make program-related investments.
