Common questions
Which foundations give to nonprofits in Seaford, New York?
Jeff and Marieke Rothschild Foundation, The Peter J Haller Family Foundation, The Gagnon Family Foundation Inc (fka the Lois E & Neil J Gagnon Foundation), Clark Gillies Foundation, The Wallace Foundation and 14 others reported grants to Seaford 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 Seaford. Community foundations and corporate giving programs file different forms and are not included yet.
