Ideal Applicant
A registered 501(c)(3) proposing a discrete project or special initiative, especially arts, education, or medical/health programs with a clear California impact (though out-of-state projects with strong ties have been funded).
Good Fit
- • Clear, project-specific request rather than unfocused general operating support
- • Demonstrable impact or activities in California or a strong CA connection
- • Arts, education, or medical/health mission alignment
- • Ability to supply EIN, IRS determination letter, organizational history, and a concise project use statement
- • Capacity to manage mid-size to large grants (range includes multiple seven- and six-figure awards)
Geography
Observed giving is heavily California-focused: in the latest year 85% of dollars stayed in the foundation's home state despite grants reaching 20 states.
Recipient Variety
The latest year shows a broad recipient set—139 distinct grantees across arts, education, medical and other categories—so the foundation funds many independent organizations despite some dollar concentration among top recipients.
New Applicants
Direct application instructions, a named mailing contact, a June 1 deadline, and a high share of new grantees in 2023 (about 68 new recipients) indicate unfamiliar applicants have a plausible path into the portfolio; three years of filings also show repeated turnover.
