School Overview

Tucked away in the rural eastern edge of Contra Costa County, Old River Elementary has a small-town feel that's increasingly rare as Brentwood continues to grow — families here tend to value that tight-knit community atmosphere where teachers actually know your kid by name. Academics are solid across the board, with math being a particular strength, making it a good fit for families who want dependable public education without the pressure-cooker environment of more competitive Bay Area suburbs. If you're drawn to the idea of wide open spaces, farm country, and a slower pace of life while still being within reach of the broader East Bay, this corner of Brentwood has a genuine charm that newer developments in the area can't quite replicate.
