Ideal Applicant
Small-to-medium community nonprofits (especially in Marin County/San Geronimo Valley) or regional conservation, education, job-training, and social service groups seeking modest general operating or program support, or organizations that can receive funds via a community foundation/DAF.
Good Fit
- • Programs or beneficiaries located in Marin County or nearby Northern California communities.
- • Requests labeled as general support, annual fund, job training, or local park/environment projects.
- • Ability to provide 501(c)(3) verification and a concise statement of grant purpose.
- • Existing relationship or referral through local community foundations or donor-advised funds.
Geography
Grants in the latest year touched recipients in nine states, but 56% of dollars remained concentrated in California, indicating a regional (state-centric) footprint with some out-of-state giving.
Recipient Variety
The latest filing shows 37 distinct recipients and a large number of small grants, and the foundation added 24 new recipients in the latest year, so the observed recipient set is broad despite dollar concentration in a few pass-through gifts.
New Applicants
Direct evidence shows many new grantees in the latest year and the foundation provides application instructions plus a named contact and mailing address, so unfamiliar applicants have a plausible path to be considered.
