Common questions
Which foundations give to nonprofits in Mount Rainier, Maryland?
Louise P Toole Charitable Trust, The Morris and Gwendolyn Cafritz Foundation, The Esther a & Joseph Klingenstein Fund Inc, Pepper Whiston Foundation, Alexander McCausland Charitable and 27 others reported grants to Mount Rainier 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 Mount Rainier. Community foundations and corporate giving programs file different forms and are not included yet.
