About Thomas W Haas Foundation
The Thomas W. Haas Foundation concentrates its giving on a mix of regional New Hampshire civic infrastructure and environmental conservation, while also supporting national cultural and health institutions. Large, multi-grant investments fund watershed and forest resilience in New England, capacity-building through the New Hampshire Community Foundation, and selective national partners such as the Smithsonian; there is also targeted support for Native American community needs and health administration initiatives.

About Thomas W Haas Foundation
A defining feature of the Thomas W Haas Foundation is its repeated, high-dollar support for New Hampshire civic infrastructure and landscape-scale conservation, alongside a smaller set of national institutions. The largest recent grant in the file is $4.5 million to Nhcf, and the foundation also gave $3 million to Building a Resilient Great Bay in 2025 and $2 million to the Smithsonian Institution that same year. Those gifts sit within a broader pattern of six- and seven-figure awards that fund community capacity, watershed resilience, forest stewardship, cultural institutions, and targeted health and Native American community needs. The record shows the foundation making multiple grants over several years to the same recipients, including the New Hampshire Community Foundation, Building a Resilient Great Bay, the Smithsonian Institution, the Rosebud Sioux Tribe, and the Northern Forest Center Forest Fund Campaign. Smaller grants also appear in arts, aviation, and health-administration support, indicating a portfolio that mixes long-term place-based commitments with selective institutional funding. The foundation’s giving is regional in scope, but its recipient list reaches beyond New Hampshire into Washington, South Dakota, and other states through named partners.
What Thomas W Haas Foundation Funds
In New Hampshire civic infrastructure, the foundation gave $4.5 million to Nhcf in 2025 and $3 million in 2023, signaling a repeated commitment to community capacity-building through that intermediary. For estuary and coastal work, it awarded $3 million to Building a Resilient Great Bay in 2025 after earlier grants of $1.5 million in both 2024 and 2023. Forest stewardship is another recurring thread: the Northern Forest Center Forest Fund Campaign received $750,000 in 2025 after $250,000 grants in 2024 and 2023. The foundation also supports targeted health and social needs, including $924,600 to Mgh Health Administration in 2025 and $500,000 to New Hampshire Tomorrow Sunstance Use Disorders Fund in 2023.
How Thomas W Haas Foundation Gives
Typical grants are modest at the lower end but include many large exceptions: the p25 is $2,500, the median is $5,000, and the p75 rises to $162,500. The file also shows repeated awards across multiple years to several recipients, which points to continuing support rather than one-off giving. Grantmaking appears to be through charitable grants, with no program-related investments and no grants to individuals. The recent record includes both very small awards and multi-million-dollar commitments, suggesting a portfolio that uses a few large anchors alongside many smaller grants.
