Welcome to our Montessori School

The Montessori School of San Leandro is dedicated to providing a nurturing and stimulating environment for children to grow, learn, and thrive. Our school has proudly served the San Leandro, Castro Valley and surrounding communities since 1995 offering an excellent educational approach based on the principles of Maria Montessori.

We believe each child is a unique individual with limitless potential. Our experienced and passionate teachers foster a love for learning by creating a hands-on and child-centered environment. We offer programs for children from the age of two through kindergarten, providing a seamless educational journey during these critical early years.

We are dedicated to cultivating lifelong learners who possess a love for knowledge, strong character, and the skills necessary to succeed in an ever-changing world. We invite you to join our close-knit community and experience the transformative power of Montessori education.

Our School Programs

Two-Year Old

Your two-year-old is rapidly developing into a competent, independent child ready to face new challenges. Our excellent program is designed to meet, support and develop your child’s emerging skills. Our curriculum develops essential social, emotional, and cognitive skills.


Nurture your child’s interest in learning by exploring language, including reading and writing, mathematics, sensorial, practical life competency skills, and studying plants, animals, geography, land and water forms, and continents and oceans in a culturally inclusive environment.

Summer School

Our exciting Summer School program alternates each summer from Human Anatomy - 2024, Solar System - 2025, and Invertebrate Animals - 2026. Models, puzzles, books and projects, and arts and crafts are a part of the experience for your child.

Things you should know

All teachers have state-required units in Early Childhood Education, CPR and First Aid Training, Mandated Reporter Training, and Criminal Background Checked. Most hold higher education degrees and Montessori credentials through Montessori accredited training programs or are currently in training to ensure we maintain highly qualified staff.

Our Montessori school follows the state requirement ratio of one teacher visually observing and supervising at most 12 children in attendance. Every classroom consists of a head teacher and two qualified assistants for a group as large as 36 students.

Our staff and children’s safety is our highest priority. Policies and guidelines are in place to provide a safe and healthy environment for all visitors, including: touchless attendance system, motion-detecting hand sanitizers, daily sanitizing and janitorial in a safe enclosed campus with external security cameras, access code entry, and a emergency disaster plan.

This is such a great preschool! Both my son and now my daughter is attending. Director Sarah does such a great job and is so professional and so are all the teachers. The curriculum, approach to encouraging kids to explore and learn on their individual path to self discovery is enlightening! Both my kids have learned so much socially and academically. I highly recommend their program!

A big shoutout to Ms. Amela! She is an outstanding teacher and her experience in Montessori methodology clearly shows. My oldest was able to read, write and do basic arithmetic before kinder thanks to her. And we are lucky to have her for our second child as well. She communicates well with parents and has an authentic concern for the child education and development.

My son is now 4 and in the past year he's attended Montessori of San Leandro, he's improved so much in his drawing, writing, and letter recognition (including their sounds). He writes his name independently and is practicing other letters, too. He also knows simple math concepts and can do very basic math problems, like adding and subtracting single digits. He's happy, confident, making friends, and learning so much. Though our communication with the school is not frequent, I find that any email or question I have is answered immediately.

My kids started attending this school seven years ago, and we are still happy with our choice, we met the current director Ms. Sarah since day one, she took care of my kids like a second mom, they grew with her academically & emotionally, and she was able to deal with the different personalities in a great way, she is so dedicated to her job, and with her love she became as a part of our family.

Our two year old son started in room 4 this year with Ms. Howida, along with Ms. Reina, and Ms. Noemi. Not only is he incredibly happy at this school, he is learning so much. He constantly talks about Ms. Howida and his friends from school. Ms. Sarah, the school director, is organized, energetic, and loving. We are so grateful that we found Montessori of SL!
