Common questions
Which foundations give to nonprofits in Islip Terrace, New York?
The Jacob Marley Foundation Inc, Adams Family Foundation, The Stringer Foundation, Knapp-Swezey Foundation Inc, Lucille T Stretch and George J Stretch Charitable Foundation Inc and 5 others reported grants to Islip Terrace 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?
