The Daddario Charitable Foundation concentrates its giving on a single large education commitment alongside targeted support for local cemetery upkeep and biomedical research at major Boston hospitals. The foundation’s largest recipient by far is The Taft School, receiving multi-year scholarship aid, while much smaller, recurring gifts fund cemetery maintenance and cancer/hematology research at Massachusetts General and Brigham & Women’s. Giving appears locally focused in New England and mixes one transformational education gift with a pattern of modest institutional philanthropic support.
The Daddario Charitable Foundation C/o Joseph P Costello Cpa is defined by a single large scholarship relationship with The Taft School, including a $503,000 grant in 2025 and two $500,000 grants in 2023. That education commitment sits alongside a smaller pattern of institutional gifts for cancer research and cemetery upkeep. The foundation’s recent giving shows a narrow portfolio: one major recipient for scholarship aid, plus repeated support for Boston-area hospital research and a North Attleborough cemetery organization. Across the recent grants list, the same core areas appear again and again: scholarship aid for individual students, cancer research at major hospitals, and cemetery maintenance. The structure of the giving suggests a foundation that uses one transformational education grant to anchor its activity, while continuing modest project support in a few local institutions. The largest grants go to a boarding school in Connecticut, while the other recurring gifts are much smaller and tied to specific operating needs or research funds. The foundation’s profile is therefore less about broad thematic diversification than about concentrated support for a small set of education and community institutions.
Scholarship aid is the clearest thread in the foundation’s grantmaking. The Taft School received a $503,000 grant in 2025 for scholarship aid to individuals, following two $500,000 grants in 2023 for the same purpose. In cancer research, the foundation gave $3,500 to Brigham & Women’s Hospital in 2023 and again in 2025, both for cancer research. It also supported the Experimental Hematology Fund Mass General Hospital with $3,500 grants in 2023 and 2025. For cemetery preservation, Friends of Mount Hope Cemetry received $3,500 in 2023 and another $3,500 in 2025 for cemetery maintenance. The pattern points to project-specific support rather than broad operating grants across unrelated causes.
The grant-size pattern is tightly clustered at two levels: p25 $3,500, median $3,500, and p75 $3,500 for the smaller grants, with a separate multi-hundred-thousand-dollar scholarship commitment to The Taft School. The recent record also shows repetition across years: The Taft School appears in both 2023 and 2025, Brigham & Women’s Hospital appears in 2023 and 2025, Mass General Hospital appears in 2023 and 2025, and Friends of Mount Hope Cemetry appears in 2023 and 2025. The foundation is a private charitable foundation, not a program-related investment vehicle, and it funds individuals directly through scholarship aid.

Highly concentrated: one very large, repeat multi-grant commitment to a single school combined with several small, recurring grants to a handful of local institutions (hospitals and cemetery). Predominantly repeat grantees rather than broad, one-off grants.
Notable grantees: The Taft School, Friends of Mount Hope Cemetery, Massachusetts General Hospital (including Experimental Hematology Fund), Brigham & Women’s Hospital
