What Healthcare Foundation Northern Sonoma County does
Mission
We connect people and resources to promote wellness in underserved communities.
As stated on its FY2025 Form 990.
Program
The healthcare foundation raises funds in support of underserved communities in our region, from northern santa rosa to the mendocino border. With a commitment to increasing health equity, we focus our grant support on equitable access to healthcare and mental health services. In 2025 we continued our support for local health clinics and grassroots community-based organizations that focus on low-income, vulnerable populations. We also continued to fund scholarships for bilingual, bicultural mental health professionals who agree to stay in our area and serve in clinics, schools, and nonprofits to address the extreme shortage of bilingual providers, and to improve community health.

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 2017 to 2018, from $690k to $1.6M (+125%).
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: 2021 5%. Grants only. Government contracts and fees sit inside program revenue.

78% 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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $2.1M 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.
