Common questions
Which foundations give to nonprofits in Mayo, Maryland?
The Keith Campbell Foundation for the Environment Inc, The Oak Hill Fund, Chesapeake Power Foundation Inc, Argyll Foundation, White House Farm Foundation and 6 others reported grants to Mayo 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 Mayo. Community foundations and corporate giving programs file different forms and are not included yet.
