Common questions
Which foundations give to nonprofits in Sonoma, California?
Khr McNeely Family Foundation, The Vadasz Family Foundation, Kalmanovitz Charitable Foundation, The Heising-Simons Foundation, Clay Foundation - West and 95 others reported grants to Sonoma 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 Sonoma. Community foundations and corporate giving programs file different forms and are not included yet.
