Arcadia Montessori School is offering an after-school day care program for children from our surrounding community including siblings of our students ages 2-6.

We’re excited to announce that our preschool now offers after-school care until 6:00 PM! This new option provides a safe, nurturing environment for children to continue learning and playing while giving parents added flexibility in their schedules. Our caring staff will lead engaging activities and ensure a smooth transition from the school day to after-school care. We’re here to support your family—please reach out to learn more or to enroll in our extended day program! (OPTIONS Accepted).

Welcome to Arcadia Montessori School – Inspiring Young Minds Since 1963

Discover the oldest Montessori school in the San Gabriel Valley, where our legacy of excellence has empowered children aged 2–6 for over 60 years.

We Nurture Independence Through the Montessori Method

At Arcadia Montessori School our mission is to provide a warm, nurturing, safe environment that will guide children to develop to their fullest potential. Through a prepared environment each child is encouraged to learn and explore their interests and natural curiosity with hands-on materials, mixed-age classrooms, and trained teachers. Our goal is to build confidence, creativity, and a love for lifelong learning.

Programs That Grow with Your Child
Toddler & Primary (Ages 2–6): Emphasizing practical life, sensorial, language, math, and cultural studies—each at the child’s pace.

In mixed-age environments, students deepen their leadership, literacy, numeracy, and we even offer Dance, Gymnastics, and Chinese Language Immersion.

Expert Faculty & Loving Community
Guided by Owner-Director Cheryl Roberts—since 1976 and holding a Speech Pathology degree from CSULA—our teaching team is fully Montessori-trained and vetted (CPR-certified, live-scanned). We’re a multi‑generational school: many of our staff attended Arcadia Montessori themselves!
