Board of Trustees
The Board of Trustees, comprised of a dynamic, talented group of professionals with a wide range of expertise, works collaboratively with the Administrative leadership team to provide strategic direction, advance River's mission, and ensure financial well-being.

- Expand student enrollment and retention
- Increase teacher retention
- Serve more children from marginalized communities by attracting new funders for the Community Outreach Fund
- Protect the school's inclusive community
- Conduct a successful capital campaign & secure bond financing
- Complete the purchase of a new campus
