The Sidney and Deanna Wolk Family Foundation makes a small number of very large, unrestricted grants focused on Greater Boston institutions that deliver health care, food security, and services for older adults. Their portfolio is highly concentrated — multi-million dollar general-purpose gifts to a major hospital, the regional food bank, and a Jewish-affiliated senior services provider — indicating a preference for established nonprofits addressing basic needs and health in their local community.
The Sidney and Deanna Wolk Family Foundation stands out for its large, unrestricted support to a small set of Greater Boston institutions. Its biggest recent grant was $3,000,000 to Mass General Hospital, a sign of how heavily the foundation leans toward established providers of health care and core community services. That same pattern appears in its giving to Greater Boston Food Bank, which received $1,000,000 in 2024 and another $1,000,000 in 2025, and to Hebrew Senior Life, which received $1,060,000 in 2023 and $542,949 in 2024. Those gifts show a funder that favors general-purpose support rather than narrowly restricted project funding. The portfolio also includes grants to Boston Medical Center, Dana Farber Cancer Institute, and Boston-area Jewish organizations, suggesting an emphasis on health infrastructure, food access, and services for older adults. Recipients are clustered in Boston and nearby communities, with repeated support going to the same organizations across multiple years. That repeated pattern, combined with the scale of the awards, points to a foundation that backs core operating capacity at long-standing institutions serving local needs.
In health care, the foundation gave $3,000,000 to Mass General Hospital for general support and later awarded $50,000 to Dana Farber Cancer Institute. Boston Medical Center also appeared multiple times in the recent grants list, with awards of $50,000, $30,000, and $30,000. Food security is another clear area of support. Greater Boston Food Bank received $1,000,000 in 2024, another $1,000,000 in 2025, and $50,000 in 2023, showing repeated backing for regional hunger relief capacity. Older-adult services are also central. Hebrew Senior Life received $1,060,000 in 2023 and $542,949 in 2024, both listed as general grants. The foundation’s grants also include Jewish-affiliated organizations such as Cjp and Temple Emunah, alongside senior services.
The Sidney and Deanna Wolk Family Foundation’s typical grant size is $11,250 at the 25th percentile, $25,000 at the median, and $50,000 at the 75th percentile. That said, the recent-gifts list shows a highly concentrated structure with a few very large awards alongside smaller general grants. Recipients appear across multiple years, including Greater Boston Food Bank, Hebrew Senior Life, Boston Medical Center, and Cjp, which points to recurring support for core institutions rather than one-time-only giving. All listed awards are general grants. The foundation is a family foundation and does not fund individuals or make program-related investments.
