The Plum Bush Foundation’s giving is highly concentrated and appears donor-directed: roughly 80% of reported dollars went to a single community foundation tied to the Yellowstone Club, with the remainder supporting Jewish communal services, civil rights advocacy, and a tech education nonprofit. Grants are few but large, suggesting strategic, high-dollar gifts rather than broad small-dollar philanthropy. The mix of recipients points to personal or regional ties (Yellowstone Club) and an interest in Jewish elder care and Jewish civil-rights work, with a smaller interest in tech access for students.
Highly concentrated giving: one very large grant dominates the portfolio, supplemented by a small number of targeted mid-size grants. Few total grants and no obvious repeat grantees suggest occasional, donor-directed investments rather than ongoing multi-year operating support to a broad set of organizations.
A single $1,000,000 unrestricted grant to the Yellowstone Club Community Foundation stands out in Plum Bush Foundation C/o Kingsley Business Service Inc’s recent record and sets the tone for a grantmaking pattern built around large, flexible gifts. The foundation’s 2025 filing shows annual grants of $1,552,424 against $16,326,910 in assets, with a typical grant size centered at $25,000 and a higher end at $35,000. Its recent awards also include a $144,444 unrestricted grant to Hebrew Seniorlife Inc and a $50,000 unrestricted grant to Anti Defamation League, showing attention to both community-based philanthropy and Jewish communal or civil-rights work. Another $50,000 unrestricted grant to Codepath adds a technology-access thread to the portfolio. The recent record is narrow rather than broad, with a small set of large awards and a strong preference for unrestricted support. The mix of recipients suggests a foundation that uses flexible grants to support institutions across several distinct areas rather than funding many project-specific awards.
Jewish elder care is one clear line of support: in 2024, the foundation gave $144,444 to Hebrew Seniorlife Inc in Roslindale, Massachusetts, as an unrestricted grant. Civil-rights and anti-defamation work also appears in the record, with a $50,000 unrestricted grant to Anti Defamation League in New York in 2024. Technology access is another theme: the foundation gave $50,000 unrestricted to Codepath in San Francisco in 2024. Its recent grants also reach local community and education settings, including $30,000 to Beaver Country Day School in Chestnut Hill and $25,000 to Boston Medical Center in Boston, both unrestricted. Across these areas, the same pattern shows up: support is flexible rather than earmarked to a narrow project.
The foundation’s typical grant size is $5,000 at the 25th percentile, $25,000 at the median, and $35,000 at the 75th percentile, but the recent record also includes much larger awards at the top end. Grants appear to be one-off or limited-repeat support rather than a steady, broad roster: most recipients show up once in the recent list, while a few organizations appear more than once across 2023–2025. The foundation is not reported to fund individuals and does not make program-related investments. Recent grants are consistently unrestricted, indicating a preference for flexible operating support over project-restricted funding.
