Common questions
Which foundations give to nonprofits in Geyserville, California?
William H Hinkle Charitable Foundation Inc, Brt Charitable Foundation, The Stanley S Langendorf Foundation, Syar Foundation Susan L Syar Director, Messing Family Charitable Foundation and 8 others reported grants to Geyserville 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 Geyserville. Community foundations and corporate giving programs file different forms and are not included yet.
