School Overview

Tucked into the laid-back, creative energy of Petaluma — a small city in Sonoma County known for its Victorian architecture, farm-to-table culture, and strong sense of community — River Montessori Elementary Charter is a natural fit for families who want something a little different from a traditional classroom experience. The Montessori approach here pairs beautifully with Petaluma's independent, hands-on spirit, and the school's strong English scores suggest kids are developing real depth as thinkers and communicators. Families drawn to self-directed learning, mixed-age classrooms, and a school that feels like a genuine community rather than just a building will find a lot to love here.
