Huron Foundation is a private corporation based in PHILADELPHIA, PA. The foundation received its IRS ruling in 2008. The principal officer is Marilyn C Sanborne. It holds total assets of $4.3M. Annual income is reported at $189K. Total assets have grown from N/A in 2010 to $6.2M in 2022. The foundation is governed by 3 officers and trustees. Tax records are available from 2021 to 2023. The foundation primarily funds organizations in Pennsylvania and District of Columbia. According to available records, Huron Foundation has made 42 grants totaling $787K, with a median grant of $10K. Individual grants have ranged from $1K to $100K, with an average award of $19K. The foundation has supported 21 unique organizations. The foundation primarily supports organizations in Pennsylvania, District of Columbia, New York, which account for 95% of all grants. Grantmaking reaches organizations across 4 states. Contributions to this foundation are tax-deductible.
Huron Foundation is not a staffed, publicly-facing grantmaking institution — it is a closely-held Cohen family foundation chaired by Rhonda R. Cohen (President), with Benjamin J. Cohen as Secretary/Treasurer, Joshua S. Cohen as Director, and Ambassador David L. Cohen (former Comcast Executive VP and U.S. Ambassador to Canada, 2022-2025) listed as an officer. Founded in Philadelphia in February 2008 (EIN 26-1512121), it operates with zero paid staff, and all four family officers serve without compensation. Filings are administered out of a Center City Philadelphia office address (1735 Market Street, 51st Floor), with an accountant/attorney of record (Marilyn C. Sanborne) rather than a grants department. That structure shapes everything about how it gives: decisions run through a four-person family board rather than program officers reviewing unsolicited proposals.
The grantee data confirms this. Of the 21 distinct organizations funded in the period captured, nearly every one received exactly two disbursements in the year — a pattern consistent with a board that meets a handful of times annually and re-funds known relationships rather than running an open competitive cycle. Recipients cluster around institutions with a direct personal tie to the family: Germantown Friends School (where the Cohens endowed a scholarship fund in 2025 with input from sons Joshua '08 and Benjamin), the University of Pennsylvania Carey Law School ($50,000; David Cohen chairs Penn's Board of Trustees), and the Council for Canadian American Relations ($50,058; tied to David Cohen's ambassadorship).
For first-time applicants, the practical read is blunt: this is very unlikely to be a cold-application funder. There is no program staff to review an unsolicited letter of inquiry, the foundation's own IRS filing lists application instructions as none, and giving skews overwhelmingly toward repeat support of pre-existing relationships in Philadelphia's education, youth-sports, health/human-services, and civic-engagement sectors. Organizations most likely to break in are Philadelphia-based nonprofits with a genuine connection point to the family's institutional affiliations — Penn, Comcast/NBCUniversal philanthropy, Jewish Philadelphia community networks (David Cohen explicitly invokes tikkun olam), or youth-sports/access programming, the closest thing to a stated thematic thread in the data. A warm introduction beats a mailed proposal every time here.
The database captures 42 grants totaling $787,164 across 21 organizations (average $18,742; median $10,000), with individual grants ranging from $1,000 to $100,015 in the most recent full year tracked. By program area, the cumulative giving breaks down roughly as: youth sports and enrichment 34% ($270,030 — Philadelphia Youth Basketball $200,030, ESF Dream Camp Foundation $60,000, Philadelphia Youth Sports Collaborative $5,000, KaBOOM $5,000); Latino/immigrant services and civic ties 25% ($200,134 — UnidosUS $100,076, Puentes de Salud $50,000, Council for Canadian American Relations $50,058); child welfare and human services 19% ($150,000 — Support Center for Child Advocates $70,000, Children First $40,000, Share Food Program $20,000, Ronald McDonald House $10,000, Planned Parenthood $10,000); education 10% ($80,000 — Penn Carey Law School $50,000, Swarthmore College $20,000, Chestnut Hill College $10,000); arts and media 7% ($55,000 — Quintessence Theatre Group $40,000, WHYY $10,000, FringeArts $5,000); with National Urban League ($20,000), Penn Medicine ($10,000), and Interfaith Philadelphia ($2,000) rounding out the remainder. Geographically, 30 of 42 grants (71%) went to Pennsylvania organizations, with 6 to DC, 4 to New York, and 2 to Illinois.
Over time, the foundation's own IRS filings (by fiscal year in this database) show a fairly steady payout of $217,531-$393,582 annually between 2018 and 2022, tracking against total assets that peaked around $8.4M in one of those years before settling near $4.3M today. Third-party analysis of more recent 990-PF filings shows a marked contraction: just 6 grants totaling $285,000 in the most recent reported year and 6 grants/$280,142 the year before — down from 14-24 grants in 2019-2022 — even as the single largest gift on record, $110,000 to Germantown Friends School in 2025, set a new high-water mark. That combination (fewer grants, one much larger gift) points to a foundation consolidating its giving into fewer, deeper relationships rather than a broad annual pool, which materially lowers the odds for an organization without an existing tie.
| Foundation | Assets | Annual Giving | Primary Focus | Application |
|---|---|---|---|---|
| Huron Foundation (PA) | $4.3M | ~$280K-$390K/yr (6-21 grants) | Philanthropy & Grantmaking — Philadelphia youth, education, civic ties | Relationship-based; no public LOI process found |

| Brooks Foundation (WY) | $4.3M | Not disclosed | Philanthropy & Grantmaking | Not disclosed; no public website |
All six foundations sit in a remarkably tight $4.30-4.31M asset band and share the same NTEE classification, which likely reflects how this dataset's peer-matching works (assets-proximity) rather than true strategic similarity — none of the five peers has an associated website on file, and none discloses an annual giving figure or application process. That absence is itself informative: sub-$5M family foundations classified under Philanthropy & Grantmaking overwhelmingly operate without dedicated staff, public web presences, or formal application processes, and Huron fits that same closely-held mold despite the website URL on file (which, per this research, actually belongs to an unrelated same-named Ohio charity — see recent activity). Grant seekers should treat this entire peer set as requiring personal introduction rather than cold outreach, and should not expect any of them to publish deadlines or portals.
The most concrete recent activity is the Cohen family's 2025 gift establishing an endowed scholarship fund at Germantown Friends School through the Huron Foundation, reported by GFS on March 12, 2025. Ambassador David L. Cohen — a GFS-connected Philadelphia figure best known as former Comcast Executive Vice President and U.S. Ambassador to Canada (2022-2025) — framed the family's giving around the Jewish concept of tikkun olam ('repairing the world'), saying 'education is the ultimate leveler of the playing field' and that a strong institution has 'a special importance to make sure there is access to the institution for all, regardless of income level, race, or the neighborhood where you grow up.' Rhonda R. Cohen, the foundation's chair, added: 'It's really about removing obstacles, and money is too often a big one.' The gift, made with input from sons Joshua ('08) and Benjamin, was the largest single grant identified in this research at $110,000, exceeding the largest amount ($100,015) captured in the foundation-level database.
Beyond that gift, third-party 990 tracking shows the foundation's grantmaking volume has fallen to just 6 awards per year in the two most recent reported years (versus 14-24 previously), while assets have declined from a mid-decade peak near $8.4M to roughly $4.3M today. No independent press coverage of the foundation itself (as distinct from the GFS story) surfaced in this research — it maintains a low public profile consistent with its no-staff, family-board structure. One important research finding for future grant seekers: the domain huronfoundation.org, which appears in this foundation's on-file website field, actually describes an unrelated organization — a hospital-legacy charity in East Cleveland, Ohio, serving that community's health programs — and should not be used to contact or apply to this (Philadelphia) Huron Foundation.
There is no evidence of a public letter-of-inquiry portal, online form, or published deadline for this foundation (EIN 26-1512121, Philadelphia, PA) — its own IRS filing lists application instructions as none, consistent with a four-person, all-volunteer family board and zero program staff. Do not use huronfoundation.org's 'Apply for Grant' page; that site belongs to a different, unrelated Ohio-based hospital-legacy charity restricted to East Cleveland/Cleveland Heights health programs, not this funder.
The realistic path in is a warm introduction. Ambassador David L. Cohen chairs the University of Pennsylvania's Board of Trustees, giving Penn-affiliated organizations and initiatives a natural point of connection (reflected in the $50,000 grant to Penn Carey Law School and $10,000 to Penn Medicine). The family's ties to Comcast/NBCUniversal philanthropic circles, the Germantown Friends School community (where they endowed a scholarship in 2025), and Jewish Philadelphia community and civic organizations (David Cohen explicitly cites tikkun olam as a guiding value) are all plausible entry points. An introduction from an existing grantee — Quintessence Theatre Group, Support Center for Child Advocates, Puentes de Salud, or Share Food Program among them — is also a credible route.
Align proposal language to the family's own stated framing: 'access,' 'removing obstacles' (Rhonda Cohen), and 'leveling the playing field' (David Cohen), and connect the ask to one of the four categories that account for roughly 88% of cumulative giving — youth sports/enrichment (34%), Latino/immigrant services and civic programs (25%), child welfare/human services (19%), and Philadelphia-area education (10%). Every one of the 42 recorded grants funded general operating budgets rather than restricted programs or capital projects, so a general-support ask is the safest framing. Keep a first-time request in the $5,000-$50,000 band, which covers 19 of the 21 distinct grantees on record; the one six-figure gift ($110,000, Germantown Friends School) went to an institution with a decades-deep personal tie to the family, not a new relationship. Because total grant volume has fallen to just 6 awards per year in the most recent filings — down from 14-24 previously — competition for a new slot is tighter than the historical grantee count suggests, and patience with a multi-month cultivation timeline (not a single competitive RFP cycle) is essential.
