The John A Thomann Memorial Foundation concentrates its giving on health care—particularly cancer treatment and patient-support initiatives—while also consistently supporting first responders, veterans/military transition programs, and local community social services. Grants tend to be program/general support to established organizations rather than small grassroots projects, and the foundation combines a few larger, repeat gifts with a range of mid-sized one-off grants across health and public-safety themes.
Concentrated giving with a flagship beneficiary (Memorial Sloan Kettering receives ~40% of dollars and multiple grants) alongside a portfolio of mid-sized, mostly one-year grants; mix of repeat grantees and single gifts focused on established nonprofits rather than startups.
A $100,000 grant to Memorial Sloan Kettering Cancer Center sets the clearest tone for John a Thomann Memorial Foundation’s recent giving: health care, especially cancer treatment and patient support, sits at the center of its grantmaking. The foundation also backs organizations serving first responders, veterans, and military transition needs, along with a smaller set of local community and social-service groups. Recent awards show a pattern of mission support to established nonprofits rather than project-specific or individual aid. Its recent grants include repeated support for the same health organization across multiple years, alongside steady checks in the $10,000 to $20,000 range. That mix suggests a foundation that balances larger anchor gifts with a broader spread of mid-sized awards. Recipients include hospitals, cancer-support organizations, public-safety nonprofits, autism services, and food or resource centers. The grant list also shows that the foundation’s reach is largely regional, with most awards staying close to its New York-centered network. Within that pattern, it funds both high-profile institutions and smaller community organizations, usually with language indicating support for the organization’s mission.
Cancer-related giving is the most visible part of the foundation’s portfolio. It gave $100,000 to Memorial Sloan Kettering Cancer Center in 2023, then followed with $20,000 in 2024 and $10,000 in 2025, all for the organization’s mission. It also supported Share Cancer Support with a $15,000 grant in 2025. The foundation also funds public-safety and service organizations. In 2025 it gave $20,000 to Steven Siller Tunnel to Tower, and in 2023 it supported the NYC Police Foundation with $20,000. Health-adjacent clinical work appears in the grant to End Sepsis (share), which received $20,000 in 2025. Community support shows up in grants to Hudson Resource Center for $20,000 in 2025 and St Francis Food Pantry for $15,000 in 2023. Autism services also appear through a $20,000 grant to Paoc Autism Services in 2025.
Typical grant size clusters tightly around $20,000: the 25th percentile is $17,500, the median is $20,000, and the 75th percentile is also $20,000. That points to a fairly narrow mid-sized grant profile, with one larger outlier at $100,000. The foundation also shows repeat support to the same organization across multiple years, most clearly in the cancer portfolio. Its grants are mission-support oriented, and the profile indicates it does not fund individuals and does not make program-related investments. Leadership is listed as Norbert Rahm.
