Ideal Applicant
A medium-to-established nonprofit in the Pacific Northwest (especially Oregon) working in conservation, food security, social services, or education with capacity to manage substantial grants or capital projects and local relationships or introductions to the foundation.
Good Fit
- • Headquartered or operating primarily in Oregon or the Pacific Northwest
- • Programs in environmental conservation, food banks/food security, youth education, or social services
- • Experience managing capital projects or large grants
- • Existing local credibility or board/staff connections that can generate introductions
- • Track record of measurable community impact and sound financial stewardship
Geography
Giving is concentrated in Oregon (about three-quarters of 2024 dollars) but grants were also made to two other states, so the footprint is state/regional rather than strictly local or national.
Recipient Variety
The latest year shows 27 distinct grantees with a wide mix of missions (conservation, food banks, education, social services) and multi-year histories include 51 and 11 recipients in prior years, indicating a broad recipient set despite some dollar concentration.
New Applicants
Behavioral evidence shows frequent new grantees (17 of 27 in 2024 and many new recipients in 2023), but the public application stance is invitation-only, so unfamiliar organizations without introductions are unlikely to access the portfolio easily.
