Programs
San Mateo Medical Center & Clinic Support- San Mateo County Health Foundation provides essential funds for the medical center's growth and improvement. 150 people attended a healing program for frontline workers designed to help them learn skills and tools to care for their mental health and support their families and colleagues. Nurses from the Sexual Assault Response Team had the opportunity to be part of intensive conferences that focused on practices and emerging issues for effectively responding to gender-based crimes and exploring new research and knowledge in forensic nursing. San Mateo Medical Center patients benefitted from sterile processing and endoscopy sterilization equipment paid for in part by the foundation. A patient navigator was hired to establish trusted relationships with African American and Black patients. This ensured consistent outreach to patients in this population who experienced homelessness in our impacted communities. They also received colorectal cancer screening and blood pressure control education.

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 2022 to 2023, from $3.9M to $5.8M (+50%).
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 26% · 2024 10% · 2025 10%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 9 reported years ran a deficit.

In-state vs out-of-state, by year
