Common questions
Which foundations give to nonprofits in Port Jefferson, New York?
John T Mather Memorial Hosp UW, Mother Cabrini Health Foundation Inc, Frey Family Foundation Inc, Intuitive Foundation, Jessie Smith Noyes Foundation and 41 others reported grants to Port Jefferson 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 Port Jefferson. Community foundations and corporate giving programs file different forms and are not included yet.
