School Overview

Tucked into the laid-back, arts-friendly town of Sebastopol in western Sonoma County, Twin Hills Charter Middle School draws families who want something a little more intentional than a standard district school. Performing solidly in the top fifth of California middle schools, it hits its stride across English, math, and science — the kind of balanced academic profile that gives parents confidence without the pressure-cooker atmosphere of more competitive urban schools. Sebastopol itself has a strong community identity — farmers markets, redwoods nearby, a mix of longtime locals and creative transplants — and families who are drawn to that culture tend to find Twin Hills fits right in.
