What di Rosa Preserve does
Mission
Located in scenic Napa Valley, di Rosa Center for Contemporary Art engages its community in the connective power of art and nature through its permanent collection of Northern California art, contemporary exhibitions, and thought-provoking educational programs that inspire creativity and curiosity.
As stated on its FY2024 Form 990.
Program
Protected in perpetuity under the Napa County Land Trust, the Preserve features multiple galleries, a sculpture park, and a 35-acre lake, all located on 217 scenic acres in Napa Valley's famed Carneros region. di Rosa originated as the vision of Rene di Rosa (1919-2010), a prolific collector whose famed vineyards enabled his development of a world-class art collection.Together with his wife, Veronica di Rosa (1934-1991), he used the sale of his vineyards to build an "art park" for the greater public. The Organization was incorporated as a nonprofit public trust in 2000.Today, di Rosa presents contemporary exhibitions by Bay Area-based artists and anarray of educational programs for all ages, in addition to maintaining a permanent collection of notable works by artists with ties to the Bay Area from the mid-twentieth century to the early 2000's.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $505k to $953k (+89%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2020 17% · 2021 7% · 2022 1% · 2023 10% · 2024 12%. Grants only. Government contracts and fees sit inside program revenue.
52% of di Rosa Preserve’s revenue is contributions — about as donation-reliant as the typical peer (63% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 7 of the last 8 reported years ran a deficit.

The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 8 funders to 12 funders, grant income rose $72k → $293k.
13 of 29 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 65% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $5.5M from one payer (the payer's own filing calls it a related party, largest Rene and Veronica di Rosa Foundation). These are real filings, and they are not money di Rosa Preserve raised.
From the IRS filings of di Rosa Preserve’s funders (the co-funder graph). Top 28 of 29 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
di Rosa Preserve has a broad base — no single funder exceeds 17% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
65% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund di Rosa Preserve.
Largest funder’s share by year: 2017 28% · 2018 32% · 2019 39% · 2020 58% · 2021 36% · 2022 28% · 2023 21% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
33% of di Rosa Preserve's funders are still giving 3 years after their first grant; 52% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
65% of di Rosa Preserve's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $459k that is directly attributable, 73% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $843k arriving through sponsors registered in 9 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
