Common questions
Which foundations give to nonprofits in Castaic, California?
Margaret Thiele Petti Foundation, Nexstar Charitable Foundation, Floradon Foundation, The Sacchi Foundation C/O FIRST Foundation Advisors, Castaic High School Pack and 4 others reported grants to Castaic organizations on their latest Form 990-PF.
How do I approach a foundation that doesn't accept applications?
A foundation that checks "contributes only to preselected organizations" on its 990-PF won't review a cold proposal. Look at who it funds, find a shared board member, grantee or advisor, and ask for an introduction. Foundations that accept applications usually list a contact and deadlines in Part XV; we show that text on each foundation's page.
Is this list complete?
No. It covers private foundations (Form 990-PF filers) whose latest electronic return lists at least one grant to an organization in Castaic. Community foundations and corporate giving programs file different forms and are not included yet.
