Gives only in CA. Every grant it reported went to a single state. If you are outside it, this is not a prospect. If you are inside it, that is the strongest signal on this page: a funder with a local mandate and less competition from out of state.
This foundation funds faith-based organizations. 1 of its 15 reported grants went to churches, ministries or other religious organizations, $1,698 in total. That is what it paid, not what it says in a policy.
Gives every year. This foundation reported grants in 2023, 2024, 2025. A funder that shows up year after year is worth a letter even if this year is a no.
