The Stone Family Foundation appears to make a small number of relatively large, unrestricted operating grants focused on local faith-based institutions, small art museums, and regional land/forest conservation. Grants are directed to mission-driven organizations (church and museums) and at least one environmental nonprofit, suggesting a mix of community cultural support and conservation interest rather than broad national philanthropy.
A $50,000 operating grant to Catskill Forest Association in Arkville, New York stands out in the Stone Family Foundation’s recent giving and points to the funder’s interest in conservation, arts, and faith-based institutions. The foundation’s recent awards are mostly unrestricted operating support, with grants going to organizations that can use funds across their programs rather than for a single restricted project. That pattern shows up across very different grantees: churches, museums, land and forest organizations, and a few community nonprofits. Several grants are repeated across years, which suggests ongoing relationships rather than one-time gifts. Trinity Episcopal Church in El Dorado, Kansas received support in both 2024 and 2025, as did Coutts Museum of Art in El Dorado and Nature Conservancy in two different offices. The giving also reaches beyond one city or one cause area, with recipients in New York, Kansas, Oklahoma, Virginia, and Montana. The foundation’s portfolio includes cultural heritage institutions such as Gilcrease Museum and Philbrook Art Museum, alongside forest and watershed groups like Catskill Forest Association and Big Hole River Watershed Committee. Across these grants, the common thread is organizational support for mission-driven institutions.
In conservation, the foundation backed multiple land and watershed organizations with operating support. Nature Conservancy received $25,000 in 2025 from the Arlington, Virginia office and $20,000 in 2024 from Tulsa, Oklahoma, while Big Hole River Watershed Committee in Divide, Montana received $10,000 in both 2024 and 2025. Catskill Forest Association in Arkville, New York also received $50,000 in 2025 and $12,000 in 2024. Its arts giving includes support for museums and arts groups. Coutts Memorial Art Museum in El Dorado, Kansas received $50,000 in 2024, and Coutts Museum of Art received $35,000 in 2025. The Roxbury Arts Group Inc in Roxbury, New York received $20,000 in 2024 and $10,000 in 2025. The foundation also funded faith-based and community institutions. Trinity Episcopal Church in El Dorado, Kansas received $40,000 in 2024 and $35,000 in 2025, and Center for Comprehensive Health Practice in New York received operating support in both years.

Concentrated giving: few, sizeable grants (five total) with a strong inclination toward general/operations support; repeat funding to at least one grantee (Trinity Episcopal Church); geographically mixed but focused on specific organizations rather than many small awards.
