Quercus Fund Inc.

Quercus Fund Inc. is a tightly held family private foundation administered from Palm Beach, FL through Dudley & Shanley Inc. at 205 Worth Avenue. The Dudley family — Elisabeth C. Dudley (President), Henry C. Dudley (Vice President/Treasurer), Sarah Dudley Plimpton (Vice President), and Jane C. Dudley (Vice President) — serve as all directors with zero compensation, the definitive hallmark of personal family philanthropy rather than a professionalized grant institution.

The fund's name, Quercus (the Latin genus name for oak trees), is the clearest window into its giving philosophy: a deep affinity for forest ecology, landscape conservation, and environmental research. This is confirmed by the grantmaking record. Highstead Foundation Inc. in Redding, CT — a leading institution for northeastern forest and landscape science — has received 5 grants totaling $3,237,500, representing approximately 87% of all documented giving across 10 total transactions. Supplemental grants support healthcare (RVNA Health, Ridgefield CT, $250,000), land and water conservation in Arizona ($115,000), local journalism ($50,000), a community library in Redding CT ($50,000), and nature education in Minnesota ($30,000). The geographic clustering around Redding and Ridgefield, CT suggests the Dudley family has deep personal roots in that part of Fairfield County.

Critically, this is a closed, invitation-only grantmaker. Nonprofit databases explicitly flag it as preselected_only with no application instructions. There is no public application portal, no stated deadlines, and no RFP process. Grant seekers should not send unsolicited proposals — they will not be reviewed.

The typical path to this funder runs through personal connection to the Dudley family's existing philanthropic circles. Because Highstead Foundation is so dominant, organizations recognized by or in partnership with Highstead's research community stand the best chance of entering the family's philanthropic awareness. Conservation land trusts, forest research institutions, and community anchors in Fairfield or Litchfield County, CT represent the strongest natural alignment.

With assets at $18.1M and giving at a 15-year high of $927,000, the foundation is not contracting. Patient cultivation of authentic relationships — not proposal submissions — is the only viable strategy.

Annual grants paid by Quercus Fund Inc. have followed a consistent long-term upward trajectory: $537,500 (FY2010), $587,500 (FY2011), $637,500 (FY2012), $777,674 (FY2014), $900,000 (FY2019), $630,000 (FY2020), $790,000 (FY2021), $737,500 (FY2022), $837,500 (FY2023), and $927,000 (FY2025, per ProPublica). The COVID-era dip to $630,000 in FY2020 was temporary; giving has since recovered to record levels. Total assets grew from $11.8M (FY2011) to $18.1M (FY2025), driven by investment income. The foundation receives zero external contributions — it is entirely endowment-funded, with net investment income ranging from $44,241 (FY2019, a volatile year) to $1,380,979 (FY2020).

Concentration is the defining feature of this foundation's grantmaking. Highstead Foundation alone accounts for an estimated 87% of all documented dollars. Its 5 grants total $3,237,500, implying individual award sizes of approximately $500,000–$750,000 per grant. For all other grantees, the range is $30,000 (The Hartley Nature Center, MN) to $250,000 (RVNA Health, CT), with $50,000 being the most common award size for community-level grants.

The overall average grant across all 10 documented transactions is $373,250, but this figure is heavily distorted by the Highstead mega-grants. A more operationally useful number for smaller applicants is the non-Highstead median of approximately $50,000–$80,000.

By focus area: environmental research and education (Highstead) captures approximately 87% of giving. Healthcare accounts for 7% ($250,000 RVNA). Land and water conservation in other states accounts for 3% ($115,000 AZ). Education and local journalism together represent 3% ($130,000 combined).

By geography: Connecticut receives 80% of grant transactions and the overwhelming share of dollar value. Arizona and Minnesota have each received a single grant. There is no documented giving to Florida organizations despite the Palm Beach administrative address. The foundation disburses close to its required 5% of assets annually, meeting IRS minimum distribution requirements consistently.

The following peer foundations are matched to Quercus Fund Inc. by asset size (all clustered near $18.1M) and NTEE classification (T22, Private Grantmaking Foundations). None maintain public-facing websites in the database, typical of family foundations at this asset level.

Quercus Fund's $927,000 in annual giving represents a 5.1% payout rate on its $18.1M asset base, meeting the IRS 5% private foundation minimum distribution requirement. Among its asset-size peers, Quercus is notable for having the most publicly documented grantmaking activity and a consistently active giving record stretching back to at least FY2010. All peer foundations in this tier operate as invitation-only family grantmakers — unsolicited applications are ineffective across the entire peer group. Quercus distinguishes itself by its unusually focused single-grantee concentration (87% to Highstead) and its identifiable thematic lens (forest ecology), which gives grant seekers at least a coherent strategy for relationship-building even within a closed system.

No major news announcements, leadership transitions, or new program launches were found for Quercus Fund Inc. in 2025 or 2026. The foundation maintains an extremely low public profile, consistent with its invitation-only grantmaking model. No press releases, grant announcements, or conference appearances were identified in any news archive or social media channel, despite LinkedIn and Instagram accounts being listed in the foundation's database record.

The most recent verifiable activity comes from FY2025 990-PF data reported by ProPublica: $927,000 in charitable disbursements across 4 grants, with total net assets of $18,117,143. This is the foundation's highest documented annual giving figure. Revenue for FY2025 was $1,667,630, composed of $216,550 in dividends (13%), $1,430,329 in asset sales (86%), and $20,751 in other income — no external contributions.

Leadership has remained entirely stable across all available filings spanning at least four years: Elisabeth C. Dudley as President, Henry C. Dudley as Vice President/Treasurer, Sarah Dudley Plimpton and Jane C. Dudley as Vice Presidents, Frank E. Shanley as Assistant Treasurer, and Irina Fayman as Secretary. Christiane Mcnamara serves as Asst Treasurer/Asst Secretary. The Dudley & Shanley Inc. administrative arrangement has been in place throughout the available record period. No succession signals or board expansion have been noted. The prior-year filing showed 4 grants totaling $837,500, establishing a consistent 4-grant-per-year cadence that appears to be the new steady state.

Because Quercus Fund Inc. operates exclusively by invitation, the following tips address its actual operating model rather than a standard grant cycle.

Do not submit a cold proposal. The foundation is flagged preselected_only with no application instructions on file. There is no intake form, no portal, no RFP email, and no published deadline. The listed contact address (info@quercusfund.com) connects primarily to the investment fund entity sharing the Quercus name — the philanthropic foundation receives no unsolicited correspondence through this channel.

Enter through Highstead Foundation. Highstead Foundation Inc. in Redding, CT is the single most important gateway to the Dudley family's philanthropic network. Attend Highstead-affiliated forest ecology research events, collaborate on Highstead-led conservation projects, or secure visible partnerships with Highstead staff. Organizations that appear in Highstead's professional networks are far more likely to come to the Dudley family's attention than those approaching Quercus Fund directly.

Speak the ecological language. Frame all organizational communications around forest stewardship, native landscape research, or land conservation — not broad environmental or sustainability language. The Quercus (oak) identity is specific and signals real depth of commitment to temperate forest ecology in the Northeast. Weak alignment language will be noticed.

Be Connecticut-anchored. If your organization serves Fairfield County or Litchfield County, CT — particularly the Redding, Ridgefield, or Wilton corridor where Highstead and RVNA Health operate — make that geographic overlap explicit. Community ties to these towns carry weight with a family foundation that has funded local institutions like the Mark Twain Library in Redding for decades.

Target multi-year partnership framing. The 5-grant, multi-year Highstead relationship is the model the Dudley family prefers. Position your organization as a long-term strategic partner, not a one-cycle supplicant. Emphasize institutional longevity, rigorous research methods, or measurable conservation outcomes.

If a warm introduction exists, lead with the relationship. A mutual connection to any Dudley family member or to Frank E. Shanley is the only legitimate entry point. A brief phone call or personal note from a mutual contact asking to introduce your organization is appropriate. Do not call the Dudley & Shanley office (561-855-4742) without that prior relationship context.
