Welcome to ABC Preschool

Established in 1963, ABC Preschool & Daycare is proud to be the very first preschool in Castro Valley. For over 60 years, we have supported families by providing a clean, safe, and nurturing environment where children can grow, learn, and thrive.

Our mission is simple: to give your child the balanced foundation they need—socially, emotionally, mentally, and physically—through a Montessori-inspired approach to education.

A Montessori Approach to Learning

At ABC Preschool, we believe in guiding children through a child-centered, active learning experience. Our classrooms are designed to spark curiosity and independence, featuring dedicated areas for:

• Practical Life
• Sensorial Exploration
• Math & Language Development
• Cultural Studies
• Creative & Manipulative Materials

This structure fosters concentration, order, coordination, and independence while encouraging a lifelong love for learning.
