This small, Boston-based trust makes a handful of moderate-sized grants to distinct, mission-driven nonprofits rather than concentrating on a single sector. Recent giving shows interest in supporting literary arts/residency programs, grassroots community enterprise development, and coastal conservation. Grants are distributed across different geographies and issue areas, suggesting flexibility and opportunistic support of organizations with clear programmatic impact.
Three moderate, one-time grants ($15k–$20k) across diverse causes; limited number of awards per year with no obvious repeat grantees, indicating distributed rather than concentrated or multi-year commitments.
A series of $20,000 grants marks the trust’s most distinctive recent pattern, with support going to Middlebury Studio School and Ruth Stone House Inc in 2025. David Greenewalt Charitable Trust Geoffrey M Mason Trustee uses relatively few grants to back organizations with clear programmatic roles, including literary arts, community music, health access, and environmental stewardship. The recent record shows a trust that gives general support often, but also steps into specific initiatives such as archaeology fieldwork and wildlife education. The trust’s giving reaches both Vermont community institutions and select organizations farther afield. In Vermont, it has supported places such as Shelburne Farms, Addison Housing Works, and John Graham Housing and Services, while also funding organizations in Massachusetts, California, Pennsylvania, and New York. The mix includes arts and education groups, health and housing providers, and conservation organizations, which suggests a flexible approach rather than a single-sector mandate. Several grants point to sustained interest in mission-driven organizations that serve the public directly. General support appears frequently, and the named projects range from an archaeology expedition at Harvard University to a wildlife public education center at Bonnyvale Environmental Education Center. This combination of general operating support and targeted project funding gives a clear picture of how the trust works: modest number of grants, varied nonprofit types, and a preference for organizations with a defined local or field-based purpose.
In the arts, the trust has supported both literary and performing-arts organizations. Ruth Stone House Inc received $20,000 for general support, while Middlebury Community Music Center received $10,000 in 2025 and $10,000 in 2024. Winchendon Music Festival and Handel and Haydn Society also appear in the recent grant list, showing that music and literary programming both sit within its giving. Education and public learning are another clear thread. Harvard University received support in 2025, and Harvard University - Sardis Expedition received $10,000 in 2023 for support of the archaeology program. The trust also gave $10,000 to Bonnyvale Environmental Education Center for a wildlife public education center, and $10,000 to Fairbanks Museum for general support. Community health and basic needs are present as well. Open Door Clinic received grants in both 2024 and 2025, and Carlos G Otis Health Care Center received $7,500 in 2025. Housing and food access groups such as John Graham Housing and Services and Hunger Free Vermont also appear in the record.

Typical grants cluster tightly around the middle of the range: p25 is $5,000, the median is $5,000, and p75 is $10,000. That pattern fits a trust that makes relatively compact awards, with a small number of $20,000 grants at the top end. The grant list also shows repeat support to some organizations across multiple years, including Middlebury Community Music Center, Open Door Clinic, John Graham Housing and Services, and Harvard University. The trust is a private charitable trust, not a funder of individuals, and it does not make program-related investments.
Grantmaking is concentrated in Vermont, which accounts for the largest share of recipient locations and includes Middlebury, Vergennes, Brattleboro, Shelburne, Goshen, and South Burlington. Massachusetts is also prominent, with grants to Boston, Cambridge, Newton Highlands, and Somerville. Outside New England, the trust has funded organizations in California, Pennsylvania, and New York. All recorded grants in the data go to U.S. recipients.

Yes. Several recipients appear in more than one year, including Middlebury Community Music Center, Open Door Clinic, John Graham Housing and Services, and Harvard University. That pattern suggests the trust sometimes returns to the same organizations rather than only making one-time awards.
