Ideal Applicant
Small-to-midsize nonprofits (often in California) seeking general operating or program support in areas the foundation already funds — conservation, Jewish community services, food security, health, and social-justice causes — with modest funding needs in the $1K–$25K range.
Good Fit
- • Organization operates in California or another state the foundation has funded.
- • Budget or request size aligns with the foundation's common award range (many grants under $5K; several up to $25K–$32K).
- • Work aligns with historically funded areas (conservation, animal welfare, food banks, Jewish community services, health and social justice).
- • Has an established track record or existing relationship that would lead to nomination or preselection.
Geography
Giving is multi-state (recipients in about 15 states) but heavily weighted to the foundation's home state, which received roughly 60% of dollars in the latest year, indicating regional focus with some national reach.
Recipient Variety
Each year the foundation funds about 106–107 distinct recipients across multiple mission areas, with a substantial number of organizations funded each year and a modest share concentrated in the top five grantees.
New Applicants
Direct evidence of formal open applications is absent (the foundation states it funds only preselected applicants and no public website/contact was found), but the observed pattern shows roughly 28–35% of grantees in recent years were new, so new entrants do appear to join the portfolio—likely via nomination or introductions rather than an open application.
