The Uplands Family Foundation is a private corporation based in BEL TIBURON, CA. The foundation received its IRS ruling in 1998. The principal officer is Jeffrey & Lynn Horowitz. It holds total assets of $3.8M. Annual income is reported at $1.7M. Total assets have decreased from $6.9M in 2011 to $3.8M in 2024. The foundation is governed by 2 officers and trustees. Tax records are available from 2015 to 2024. The foundation primarily funds organizations in California and Maine. According to available records, The Uplands Family Foundation has made 219 grants totaling $1.6M, with a median grant of $3K. Annual giving has decreased from $368K in 2020 to $225K in 2023. Grantmaking activity was highest in 2022 with $678K distributed across 96 grants. Individual grants have ranged from $1K to $75K, with an average award of $7K. The foundation has supported 80 unique organizations. The foundation primarily supports organizations in California, Maine, Virginia, which account for 83% of all grants. Grantmaking reaches organizations across 10 states. Contributions to this foundation are tax-deductible.
The Uplands Family Foundation is a small, closely-held private foundation run directly by Jeffrey Horowitz (Secretary) and Lynn Horowitz (President), each drawing $45,000 in annual compensation, out of their Belvedere-Tiburon, CA home. Every third-party grant database reviewed — Grantable, CauseIQ, and Impala among them — independently confirms the same fact: it does not accept unsolicited proposals and funds by invitation only, built entirely on relationship-based giving. The foundation's own IRS filings corroborate this from the inside: no application_form_url, no grants_page_url, no stated deadline, and no published application instructions exist anywhere in its record. There is effectively no formal front door.
What exists instead is a stable, recurring portfolio of roughly 30-50 organizations funded most years, heavily loyal to a defined geography and cause set. Sixty-seven percent of tracked grants (146 of 219) go to California nonprofits clustered in Marin and Sonoma Counties — where the Horowitzes live — and another 12% (27 grants) go to Mount Desert Island, Maine, a strong signal of a second home or seasonal tie there. Within that footprint, the foundation favors independent K-8 and college-prep schools (Mount Tamalpais School, Mark Day School, Saint Patrick's School, Chatham Hall), local environmental and land-conservation groups (Pepperwood Preserve, Marin Agricultural Land Trust, Laguna de Santa Rosa Foundation), and community/immigrant-services nonprofits (Corazón Healdsburg, La Familia Sana, Canal Alliance, Aldea Children & Family Services).
For first-time or unconnected applicants, the realistic strategy is indirect: identify an organization already in the portfolio and request an introduction, surface a board or personal connection to the Horowitzes, or build visibility within the Marin/Sonoma or MDI Maine nonprofit community where the family is clearly embedded. Most funded organizations receive grants across multiple consecutive years (several appear at 3-5 grant counts in the same multi-year window), so the foundation's real pattern is deepening existing relationships rather than adding new ones — a first gift, if it comes, is likely to be modest and probationary rather than a large opening commitment.
The foundation's own typical-grant-size data (most recent full year, n=48) shows a median grant of just $2,500 and an average of $7,188, with a full range of $1,000 to $60,000 — meaning the large majority of individual checks are small, and the average is pulled upward by a handful of larger, multi-year anchor commitments. Across the broader multi-year grantee dataset (219 tracked grants totaling $1,615,500), the average grant is $7,377, reinforcing that most individual awards cluster well under $10,000 even though top relationships accumulate into six figures over time — Social Good Fund leads all recipients at $235,000 across 4 grants (avg. ~$58,750/grant, suggesting a fiscal-sponsorship or pass-through role), followed by Mount Tamalpais School ($150,000/4 grants), Heyday Books ($103,400/4 grants), and Mark Day School and Saint Patrick's School (each $100,000/5 grants).
Total annual giving has been volatile but trending downward alongside the foundation's asset base: $536,475 (FY2012) → $621,093 (FY2019) → $628,324 (FY2021) → a peak of $762,219 (FY2022) → $486,419 (FY2023), with grants paid specifically falling from the $360K-$380K range common in 2012-2015 to $224,500 in FY2023. Total assets have fallen from $6.4 million (FY2012) to $3.77 million (FY2024), a 41% decline, while officer compensation has held roughly flat to slightly up ($72,000 combined for years through 2019, rising to $90,000 by FY2022-2023).
Geographically, California dominates at 146 of 219 grants (67%), followed by Maine at 27 grants (12%), Florida (9), New York and Virginia (8 each), Massachusetts (7), Washington (6), New Jersey (5), Connecticut (2), and North Carolina (1). By cause, independent education (K-8 schools, college-prep, and a scattering of elite university gifts to Yale, Columbia, and Harvard suggesting personal alumni ties) is the single largest category, followed by environmental conservation, Marin/Sonoma community and immigrant-services nonprofits, and Mount Desert Island, Maine civic institutions (Northeast Harbor Library, MDI Historical Society, Mount Desert Nursing Association).
The five closest peers in the dataset were matched on nearly identical asset size (all approximately $3.77 million, within a few thousand dollars of Uplands) rather than on programmatic focus, and all share the same broad IRS "Philanthropy & Grantmaking" NTEE classification. None of the five have a public website on file, and no giving totals or focus-area detail were available for them in the source data, which itself illustrates a common pattern at this asset tier: most sub-$4M family foundations maintain little to no public profile.

Uplands stands out among this asset-matched peer set mainly for being unusually legible: its IRS filings and third-party grant-database coverage make its geography (CA/ME), cause areas, and typical grant size ($1,000-$60,000, median $2,500) far easier to reconstruct than any of its five peers, none of which have a discoverable website or public grantmaking narrative. That transparency gap is itself useful intelligence — a grant seeker can build a credible, targeted pitch for Uplands from public data alone, which is rarely true for foundations of this size.
Public news coverage of The Uplands Family Foundation is essentially nonexistent — a foundation of this size (sub-$4M in assets, family-run, invitation-only) generates no press releases, and none of the searches returned dedicated news coverage from 2025 or 2026. The one concrete recent data point is administrative: the foundation's most recent Form 990-PF was filed October 28, 2025, per third-party 990 trackers, consistent with routine annual compliance rather than any programmatic announcement.
Leadership has been stable and unchanged for well over a decade — Jeffrey Horowitz (Secretary) and Lynn Horowitz (President) have run the foundation together since at least the earliest financial records reviewed (FY2012), each currently drawing $45,000 in annual compensation. No new officers, staff, or program areas appear in any source.
Notably, the foundation's listed website, theuplands.org, does not currently resolve to any content about the foundation — it returns an unrelated residential-neighborhood association page ("Uplands of Scio Ridge" in Ann Arbor, Michigan). This means grant seekers cannot rely on the foundation's own web presence for current information; the only verified touchpoints are the IRS-filed contact — care of Jeffrey & Lynn Horowitz at 6 Lagoon Rd, Belvedere Tiburon, CA — and the filing contact email on record (impallari@gmail.com). Absent a functioning website or press activity, the most reliable signal of "recent activity" remains the grantee list itself: the same core group of Marin/Sonoma County and Mount Desert Island, Maine organizations continuing to receive support year over year, indicating the foundation's operations and priorities have not meaningfully changed even as total giving has declined alongside its asset base.
There is no formal application to optimize — that is the central fact to plan around. No application_form_url, grants_page_url, or deadline exists in IRS records, and three independent grant-database profiles (Grantable, CauseIQ, Impala) all state the same thing: funding is invitation-only and unsolicited proposals are not accepted. Spending time preparing a traditional LOI or portal submission for this funder will not produce a response.
The productive path is relationship-first. Because 67% of grants go to California organizations clustered in Marin and Sonoma Counties and 12% go to Mount Desert Island, Maine, the single highest-leverage move for an eligible organization is confirming genuine geographic and programmatic fit before investing any outreach effort — this is not a foundation that will consider an organization outside those two footprints without an unusually strong personal connection. Within that footprint, the funded causes are consistent enough to use as alignment language: independent K-8/college-prep education, environmental and land conservation, immigrant and community human services, and (in Maine) small-town civic institutions like libraries and historical societies.
Because several university gifts (Yale, Columbia, Harvard Graduate School) appear in the grantee list at levels too small to be strategic institutional funding, these are likely personal alumni or affinity gifts from the Horowitzes rather than open giving areas — not a template to pitch against.
If a warm introduction is secured, keep the ask modest and framed as a starting relationship rather than a large one-time need: the DB-reported typical grant is a median of just $2,500 (average $7,188, range $1,000-$60,000), and the largest relationships (Social Good Fund, Mount Tamalpais School) were clearly built up over several consecutive years rather than awarded at that scale upfront. A common mistake would be leading with a large, one-time ask; the foundation's pattern strongly favors smaller recurring gifts to organizations it already trusts. Given no disclosed deadline or cycle, timing is flexible, but approaching in the first half of the calendar year — ahead of their typical autumn 990 filing — is a reasonable default. The best evidence of fit is a specific, already-funded peer organization willing to make the introduction.
