Mission & Focus Areas
The foundation says it makes grants to private, publicly supported, not-for-profit organizations approved as 501(c)(3) tax-exempt entities. Its stated fields are education, health and human services, medical research, social services, and the arts.
In general, fundable projects include construction, expansion or renovation of facilities; capital equipment; scientific or medical research; and new or expanded programs. Capital campaign requests must be project-oriented. The foundation generally does not fund operating deficits, general operating support, endowments, loans, annual appeals, fundraising events, or unrestricted funds. It generally will not consider a request if its grant would represent majority support for the project or program; applicants are asked to provide evidence of significant support from other donors.
Examples of supported organizations illustrate varied work. Tomorrow’s Hope Foundation II describes its mission as supporting Catholic schools on Long Island through awareness, scholarships, and program funding. Hearts to Homes Furnishings says it furnishes homes for young adults aging out of foster care. Gift of Life International describes providing free medical services, primarily to children with heart defects and similar illnesses. Seatuck Environmental Association says it works to conserve Long Island’s wildlife and environment.
Grantmaking
In filing year 2025, the foundation reported 283 grants totaling $176,741. Individual grants ranged from $100 to $11,560, with a median of $400. Among the largest grants were $11,560 to St Francis de Sales RC Church in Rockaway, New York; $9,000 to St Francis de Sales (Capital Campaign) in Brooklyn; and $6,000 to Zoller Memorial Fund in Port Washington. The listed purposes for these grants were “general charitable funding.”
Other 2025 grants included $4,750 to HeartShare Human Services, $3,250 to Catholic Charities (DOB) and $3,250 to Tomorrow’s Hope Foundation II, and $3,025 to Hearts to Homes Furnishings. The foundation also reported grants to organizations outside New York, including $1,200 to Franciscan Charities in New Jersey, $1,200 to Team Rubicon in California, and $1,000 to LEAD Girls of NC in North Carolina.
How to Apply
The foundation’s website describes a two-step process. First, submit a one-page letter of inquiry describing the organization and its services, the proposed project or program, total project cost, other support and its amounts, the project schedule, and a copy of the IRS 501(c)(3) determination letter. If the inquiry appears to meet the guidelines, the foundation sends an application. Completed applications are reviewed by the Board of Trustees, which meets quarterly; its decisions are final. Applicants are asked to provide project costs, other sources of support, and the remaining need, rather than request a specific grant amount. Successful grantees must report on project completion, and the foundation will not consider a further application from the same organization until it has evidence of successful use of the prior grant and a reasonable period has elapsed.
