The Joanne & John Dallepezze Foundation concentrates its giving on major cancer treatment and research institutions, directing sizeable gifts to nationally recognized hospitals rather than local grassroots groups. Their grants are focused and repeated — multiple large gifts to the same premier cancer centers suggest long-term support for clinical care and research rather than broad-based community philanthropy.
The Joanne & John Dallepezze Foundation’s giving is defined by repeated, sizable support for cancer care institutions, especially hospital-based centers that combine treatment and research. The largest recent gift in the data was $147,500 to James Cancer Hospital in Columbus, followed by three additional grants to the same hospital in 2023 and 2024, a pattern that points to sustained institutional support rather than one-time project funding. Memorial Sloan-kettering also appears as a repeated grantee, with $100,000 grants in 2023, 2024, and 2025 for health care support. Beyond those major cancer centers, the foundation has also backed American Cancer Society, Houston Methodist Hospital, and Lungevity Foundation, reinforcing a health-focused portfolio anchored in major organizations. The grants suggest a mix of clinical care support, cancer research, and broader health-system philanthropy, with a clear preference for established institutions over smaller local organizations. In addition to oncology, the foundation has made grants in education, human services, and Alzheimer’s research, but those areas sit alongside a core emphasis on cancer-related health care.
Cancer treatment and research are the clearest throughline. In 2025, the foundation gave $147,500 to James Cancer Hospital to support health care, and it also awarded $100,000 to Memorial Sloan-kettering in 2025 for the same purpose. Research-oriented support appears as well: American Cancer Society received $42,100 in 2025 and $29,100 in 2024 to support cancer research. The foundation also backs medical and human service programming through Jdrf, which received $20,800 in 2023 and $15,000 in 2024. Education is another recurring area, with grants to Florida Gulf Coast University, Spring Branch Education Foundation, and Princeton University for support ranging from education to human services and education programs.
Typical grants are modest relative to the largest gifts: the distribution sits at p25 $2,450, median $5,000, and p75 $10,000. The recent-grants list shows both repeat support and multi-year relationships, including James Cancer Hospital, Memorial Sloan-kettering, American Cancer Society, Shelter for Abused Women, Jdrf, and Princeton University appearing in more than one year. The foundation is a private family foundation by name, and it does not fund individuals or make program-related investments. Grants are national in scope, with a mix of one-off awards and recurring institutional support rather than a formal application pattern visible in the data.

Concentrated giving: few, large grants split between two repeat grantees (three grants each). Funds flow to established, national cancer hospitals rather than a broad or geographically diverse set of small nonprofits.
Notable grantees: The James Cancer Hospital, Memorial Sloan-Kettering Cancer Center
Grantmaking reaches recipients across the U.S., with Florida accounting for 33% of grants in the dataset. Ohio is the top state by grant count, driven by repeated support for organizations in Columbus and New Albany. New York, Texas, and Illinois also appear among recipient locations. City-level giving includes Columbus, Naples, New York, Houston, Fort Myers, Princeton, Chicago, and New Albany, showing a pattern that mixes local Florida support with larger institutional grants in other states.
Its recent grants center on major cancer treatment and research institutions, especially hospital-based health care organizations. The foundation also gives to education, human services, and Alzheimer’s research, but those appear alongside a health-centered portfolio anchored in established institutions.
No. The grant list is national, with recipients in multiple states. Florida receives 33% of grants, while Ohio is the top state by grant count, and recent recipients also appear in New York, Texas, Illinois, and New Jersey.

Yes. Several grantees appear across multiple years, including James Cancer Hospital, Memorial Sloan-kettering, American Cancer Society, Shelter for Abused Women, Jdrf, and Princeton University. That pattern suggests ongoing support rather than isolated one-time gifts.
