Ideal Applicant
A nonprofit providing legal services, civil rights advocacy, or community services—especially organizations operating in California—seeking general operating support.
Good Fit
- • Organization provides legal aid, civil rights, or related social justice services.
- • Organization has an operational presence or program in California.
- • Request is for general operating support or a field-aligned program.
- • Applicant can demonstrate existing track record and local impact.
- • Organization can make a concise, relationship-oriented inquiry to the named foundation contact.
Geography
Grants appear across 15 states, so the footprint is multi-state, but giving is heavily weighted to California where roughly 70% of dollars are concentrated.
Recipient Variety
The latest year shows 77 distinct recipients with substantial year-to-year turnover (about 23 new grantees in the latest year) alongside many returning grantees, indicating a broad and diverse recipient set for the foundation’s size.
New Applicants
Direct evidence of new recipients is strong (roughly 27–30% of recipients were new in 2023–2024) and a named foundation contact is published, so unfamiliar organizations plausibly can enter the portfolio despite the absence of a formal application form.
