What Lange Foundation does
Mission
Our mission is to rescue pets that have been impounded at los angeles county's 25 overcrowded public shelters - providing proper care, shelter, and then placement. We also provide pet owners with alternatives when they think they have no other option than surrendering their pet to the shelter.
As stated on its FY2024 Form 990.
Programs
Kennel and sanctuary the foundation's kennel in los angeles and sanctuary in canyon country serve as halfway homes for dogs and cats rescued from los angeles county's 26 overcrowded public animal shelters. The foundation is the only recourse for many of the dogs and cats it rescues that require immediate emergency medical care. Prior to placement, the foundation's pets receive exceptional medical care and behavioral training, if needed. Once adopted, their progress in their new homes is carefully monitored. The foundation continues to support the animals it rescues even after they find loving homes. During the year ended december 31, 2024, 422 new rescues joined the foundation's more than 100 previously rescued animals, and 76 of the new rescues required immediate medical intervention.
$2,123,610 spent$1,873,442 earned by the program76% of program spendingThe foundation remains at the forefront of the shelter intervention movement, developing and implementing programs that provide meaningful alternatives to pet impoundment for owners facing financial hardship. These initiatives are designed to keep pets with their families by offering support when a lack of resources makes it difficult to afford food, veterinary care, or redemption fees. The foundation employs dedicated staff members stationed within the lancaster, palmdale, and san bernardino animal shelters to deliver direct assistance to pet owners in need. For the fiscal year ended december 31, 2024, the foundation covered redemption fees for 62 pets, enabling their owners to reclaim them and avoid surrender. During this same period, the foundation also facilitated veterinary services, including lifesaving surgical procedures for 150 pets, and provided food and essential supplies for 52 pets belonging to individuals experiencing homelessness. Through these targeted interventions, the foundation continues to advance its mission of reducing shelter intake, supporting responsible pet ownership, and preserving the human-animal bond within the communities it serves.
$371,672 spent$67,262 earned by the program13% of program spendingThe foundation administers the largest spay and neuter initiative in both the antelope valley and san bernardino county. During the 2024 fiscal year, the program provided spay and neuter services for 2,102 dogs and cats, representing a significant reduction in pet overpopulation within these regions. By proactively addressing the root causes of animal homelessness, the program helps prevent thousands of unwanted litters, thereby reducing shelter intake and the potential for euthanasia due to overcrowding.

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 2019 to 2020, from $7.5M to $10M (+38%).
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.
78% of LANGE FOUNDATION’s revenue is contributions — about as donation-reliant as the typical peer (81% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 8 reported years ran a deficit.

Leadership and staff
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 25 funders to 43 funders, grant income rose $133k → $354k.
14 of 103 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 45% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

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
LANGE FOUNDATION has a broad base — no single funder exceeds 18% of grant income, and it takes 7 funders to reach half.
the vertical line marks half of all grant income — 7 funders to its left
47% 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 LANGE FOUNDATION.
Largest funder’s share by year: 2017 30% · 2018 34% · 2019 23% · 2020 13% · 2021 32% · 2022 33% · 2023 27% — 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
52% of LANGE FOUNDATION's funders are still giving 3 years after their first grant; 55% 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
69% of LANGE FOUNDATION's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.4M arriving through sponsors registered in 10 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.
