Gruben Charitable Foundation

The Gruben Charitable Foundation operates from a distinctive philosophical premise: that inner growth radiates outward, and that lasting community change begins with the internal development of individuals. Founded by Diana Oehrli, who drew on an $11 million family endowment established in 2008, Gruben has disbursed over $10 million in grants to date while focusing exclusively on Aquidneck Island — the Newport, Rhode Island peninsula home to roughly 80,000 residents.

The foundation's giving philosophy rests on four operating principles that shape what proposals are funded: Trust the Body (evidence-based lifestyle medicine including nutrition, movement, sleep, and stress relief); Empower, Don't Enable (inner strength and self-reliance over dependency-creating aid); Awaken the Whole Person (integrated approaches addressing mind, body, spirit, and community simultaneously); and Give First (programs channeling personal growth into service). As founder Diana Oehrli has stated, her role is not to direct change but to steward the conditions under which change becomes possible — a framing that applicants should genuinely internalize rather than simply quote.

The typical Gruben grantee is a small-to-mid-sized Rhode Island nonprofit deeply embedded in the Newport community. Organizations including Newport Mental Health, Lucy's Hearth, Norman Bird Sanctuary, and Newport Classical have received multi-year unrestricted support, suggesting the foundation values continuity and trusts established community partners. That said, the foundation explicitly states that past grantees are not guaranteed future funding, so no relationship — however long — guarantees renewal.

For first-time applicants, the most critical filter is geographic: Aquidneck Island residents specifically, not Rhode Island broadly. Statewide organizations may qualify only when they operate programs with direct, measurable impact on Newport County communities. Proposals must align with at least one of the four pillars (Environment, Wellness, Arts & Culture, or Service & Education) and should use Gruben's own vocabulary rather than generic nonprofit impact language.

There is no letter of inquiry step — applicants submit a full PDF application during the January 2 through May 1 annual window. Review runs May through October, with notifications issued by November 30. This single annual cycle means missed deadlines cost a full year.

The Gruben Charitable Foundation has maintained consistent annual grantmaking of $640,000–$815,000 over the past decade. Annual grants paid from 2019 to 2024: $643,972 (2019), $811,144 (2020), $730,895 (2021), $690,500 (2022), $745,000 (2023), and $815,001 (2024). The most recent fiscal year represents a ten-year high in grantmaking output.

Foundation assets grew sharply from approximately $10–$11 million (2012–2020) to $17–$18 million beginning in 2021, when an extraordinary investment income event of $9.5 million more than doubled the asset base. Current assets stand at $16,965,030 (FY2024). The annual payout rate (grants paid divided by assets) has consistently hovered at 4–5%, consistent with federal private foundation minimum distribution requirements and suggesting the foundation does not plan to accelerate or wind down grantmaking in the near term.

The 2025 grant cycle distributed $815,001 across 37 organizations. Grant amounts ranged from $2,500 (Newport Global Summit) to $150,000 (Rhode Island Hospital psilocybin research). The most common award amounts clustered at $15,000, $20,000, and $25,000. At least 30 of 37 grants (81%) were for general operating support — a meaningful advantage for grantees needing flexible funding rather than project-restricted dollars. The database-reported typical grant size shows a median of $25,000 (range $4,095–$55,000 from prior cycles), though the 2025 cycle extended the upper end to $150,000 with the Rhode Island Hospital research grant.

Geographic concentration is extreme: 89% of all historical grants by count (81 of 91) went to Rhode Island organizations, with small numbers to New York (4), Massachusetts (4), and Maryland (2). The out-of-state grants reflect specific research partnerships — the BrainGate consortium at Brown University, Massachusetts General Hospital, and Weill Cornell Medicine — not a general multi-state strategy. Newport-area applicants face essentially no cross-regional competition for this funding.

For planning purposes, most new applicants should target the $15,000–$25,000 range for a first grant. The $150,000 Rhode Island Hospital grant appears to be an outlier tied to a specific clinical research relationship, not a signal of general grant inflation.

Among private foundations holding approximately $17 million in assets in the Philanthropy & Grantmaking sector, Gruben is unusual for maintaining a transparent, open application process.

Among comparable-asset private foundations in this sector, Gruben stands out as unusually accessible. Most family foundations at this asset tier operate as closed vehicles with no public-facing application process, making solicitation impossible without a pre-existing personal relationship with the family. Gruben's formal open application cycle, published eligibility guidelines, named program contact, and annual grantee disclosure represent a level of transparency rare among peers at this scale. Its tightly bounded geographic mission — Aquidneck Island exclusively — simultaneously narrows competition and sharpens funder-grantee fit: a Newport nonprofit applying to Gruben competes only against other local organizations, not the broader Rhode Island or national nonprofit field. For eligible Newport-area organizations, this combination of accessibility, focus, and $690K–$815K in annual giving makes Gruben one of the most consequential private funders available.

The most significant single grant in the 2025 cycle was $150,000 to Rhode Island Hospital for a psilocybin research project — the largest known Gruben grant in recent years and a notable signal of interest in psychedelic-assisted therapy as an evidence-based wellness intervention. This builds on prior support for BrainGate intracortical brain-computer interface research (initial seed funding to a consortium spanning Brown University, Massachusetts General Hospital, and Weill Cornell Medicine), indicating genuine appetite for supporting scientific research at the frontier of neurology and mental health.

In April 2025, Gruben and the Newport Festivals Foundation announced that their collaborative free music lesson initiative now serves over 230 students, with the program expanding through new partnerships with the Joyce & George Wein Foundation and the Bazarsky Family Foundation. Newport Festivals Foundation received $70,000 in the 2025 grant cycle in support of this work.

New grantees entering the 2025 portfolio include Maternal Health Funders of RI ($25,000 for Aquidneck Island initiatives), FabNewport ($10,000), Newport County YANA ($5,000), Newport Sings ($5,000), IYRS School of Technology and Trades ($25,000 for scholarships), and Conanicut Island Sailing Foundation ($10,000) — suggesting modest broadening into maternal health, maker education, and water-based recreation.

No leadership changes were announced in 2025–2026. Diana Oehrli remains the sole listed trustee and the contact listed in IRS filings remains % J Robert Casey. The 2026 application cycle opened January 2, 2026 with a May 1, 2026 deadline.

Aquidneck Island is the non-negotiable filter. If your organization does not primarily serve Newport, Middletown, or Portsmouth residents, do not apply. Statewide organizations may qualify only when they operate programs with specific, demonstrable impact on Aquidneck Island — the Family Service of Rhode Island's $25,000 grant in 2025 was explicitly for their Newport Go Team program, not their broader statewide work. Name the specific communities served and the number of Aquidneck Island residents reached.

Timing is everything. Applications are accepted only January 2 through May 1 each year. There is no early-bird benefit, but late submissions are not accepted. Notification comes by November 30, meaning program planning for the following year must account for a nearly year-long cycle.

Prepare your PDF before opening the online form. Name the file exactly YourOrganizationName_2026.pdf. This single file must contain: requested grant amount and purpose; organization mission summary with staff and volunteer counts; number of people served; description of alignment with Gruben's mission; explanation of how the grant will be used; current annual organizational budget (plus a separate program budget if applying for program support); a list of current funders with their contribution amounts; geographic service area description; and a list of partner organizations. If you received a 2025 Gruben grant, also include a utilization summary — this is explicitly required.

Use Gruben's own vocabulary. The foundation's philosophy is specific and intentional. Mirror their terms: inner growth, evidence-based, empowerment over dependency, whole person, stewardship, and community transformation. Avoid heavy metrics-and-outcomes language typical of government grant applications — this philosophically oriented funder responds to narrative alignment over quantitative dashboards.

General operating support is welcome. Unlike many foundations requiring project-specific requests, Gruben frequently funds unrestricted general operating support (at least 30 of 37 grants in 2025 were unrestricted). You do not need to package your ask as a deliverable-based project.

Target $15,000–$25,000 for a first grant. The median and most common award is $25,000. Requesting within this range signals awareness of the foundation's patterns without overreaching. Contact Lynne@grubencharitablefoundation.org with any eligibility or process questions — not Diana Oehrli directly.
