The Herrnstein Family Foundation concentrates its giving almost exclusively on strengthening nonprofit healthcare support organizations, primarily through large, direct grants to providers of hospital support services and platforms. Funding is highly concentrated in a very small set of recipients (notably repeated, multi-million-dollar awards to PivotWorks) and includes targeted support for patient-family services such as Ronald McDonald House in the New York area. Grants are typically sizable and program/operations–oriented rather than broadly diversified across sectors.
The Herrnstein Family Foundation’s clearest pattern is repeated multi-year support for healthcare support organizations, led by three very large grants to Pivotworks Inc in 2023, 2024, and 2025. Those awards were described as helping “the support organizations healthcare mission,” and they show a funder that concentrates dollars in a small set of mission-aligned nonprofits rather than spreading grants widely. That same pattern appears in its support for patient and family services in the New York area. Ronald Mcdonald House Charities New York Metro received $250,000 in 2023, placing family-facing support alongside infrastructure-oriented healthcare grants. The foundation also extends beyond direct patient support into related mission areas such as dental outreach in Madagascar and Center ValBio programming through Stony Brook Foundation Inc, indicating an interest in both service delivery and the platforms that sustain it. Recent grants also include health-research and allied nonprofit support organizations such as Partners in Health, Last Mile Health, and Integrate Health. The overall picture is of a regular funder that gives direct, often program-linked grants to organizations working in healthcare delivery, healthcare support services, and related mission infrastructure.
A core theme is support for healthcare mission infrastructure. In 2024, The Herrnstein Family Foundation gave $10,000 to King Baudouin Foundation United States to help the support organizations healthcare mission, and in 2024 it gave $5,000 to Cold Spring Harbor Laboratory for the same general purpose. These grants sit alongside larger commitments to organizations that assist other healthcare providers. Another visible area is dental outreach and research connected to Madagascar. In 2024, the foundation gave $100,000 to Stony Brook Foundation Inc for “dental outreach Madagascar and Center ValBio program,” and it repeated support with a $50,000 grant in 2023 for the same purpose. That pairing links the funder to both hands-on outreach and a research or field program. Education and youth-serving work also appear in the grant list. Children and Screens received $60,000 in 2024 and $50,000 in 2023, both for its exempt mission. Autism Nature Trail received $25,000 in 2024 and again in 2025.

Very concentrated giving: few, very large grants with repeat funding to the same lead grantee(s); primarily unrestricted or program support for health-related organizations, geographically focused on New York/NY metro.
Notable grantees: PIVOTWORKS INC / PIVOT WORKS INC (repeat multi-million dollar recipient), RONALD MCDONALD HOUSE CHARITIES NEW YORK METRO
The typical grant size is modest relative to the foundation’s large awards: p25 is $5,000, median is $10,000, and p75 is $50,000. The distribution shows a steep split between a few very large grants and many smaller awards. Recipients do appear across multiple years, including repeated support for several organizations and a multi-year pattern of giving. The foundation is a regular funder, not a DAF, and it does not fund individuals or make program-related investments. Unsolicited applications are not accepted in the discretionary grantmaking program described here.
The grant geography is overwhelmingly U.S.-based, with 33 grants to U.S. recipients. New York is the top state by grant count, and 52% of grants go to recipients in the HQ state. Within that pattern, New York recipients include New Hyde Park, Jericho, Castile, Saint James, New York, and Cold Spring Harbor. Outside New York, grants also went to Boston, Nashville, San Francisco, Durango, and Medway, showing a regional but not exclusive New York concentration.
Its recent grantmaking centers on nonprofit healthcare support organizations, especially groups that provide operational, platform, or back-office help to healthcare missions. The grant list also includes patient-family support, dental outreach in Madagascar, and related education or conservation-linked work.
Not through the discretionary grantmaking program described in the data. The “Discretionary Grantmaking (Global Health, Conservation, Education)” program is marked as not accepting unsolicited applications.
The typical grant size is $5,000 at the 25th percentile, $10,000 at the median, and $50,000 at the 75th percentile. That range sits alongside a few very large awards in the multi-million-dollar range.
Yes. New York is the top state by grant count, and 52% of grants go to recipients in the foundation’s HQ state. Recent New York recipients include New Hyde Park, Jericho, Castile, Saint James, New York, and Cold Spring Harbor.
The active programs emphasize global health, education, and conservation, with an added focus on capacity building and scientific research. One program also supports researchers working closely with vulnerable health care systems through a five-year unrestricted award.
