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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2017 to 2018, from $19M to $23M (+24%).
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: 2017 2% · 2018 1% · 2019 1% · 2020 1% · 2021 11% · 2022 6% · 2023 2% · 2024 2% · 2025 3%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 9 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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $707k 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.
