We are a Christian Montessori preschool that has been serving the Hillsboro School District of Oregon since 1997.
We provide an individualized preschool program that meets the unique developmental needs of each child we serve.
While they are having fun learning about math, geography, science, language, art, and music, the children are discovering something much more important - a love for learning itself.
Each exciting discovery they make helps develop their independence, inner-discipline, and self-esteem.

We absolutely love Cornerstone Montessori. Our daughter had completed her second year and our son will be starting here in the fall. It is a small class which allows the teachers to get to know all of the children and focus on them as individuals. Our daughter looks forward to going to school everyday and she comes home each day having learned something new. We give our highest recommendation for this school.

Cornerstone Montessori is a great place for independent learning! My daughter looked forward to going to school every day. The teachers made it fun and she was excited to learn. She learned basic skills, such as counting 1-100, pouring liquid into a glass, and cleaning up after doing a task. What I liked about the school is the loving environment and skills my daughter came home with that she used daily. She learned at her own pace and was encouraged to explore other activities from painting, to learning countries, addition & subtraction, & how to help others. She came home singing songs and a hunger to want to read :) I would highly recommend Cornerstone!

I found Cornerstone Montessori on-line and signed my kids up before we moved across the country, having talked to the teacher on the phone, but without having seen it. It was one of the best decisions I made while preparing to move; this school has been a tremendous blessing to our family! The kids love it, and so do I.
The teachers are warm, loving, and flexible. My kids come home singing new songs every day, and often surprise me with what they''ve learned at school. I really love the four-day schedule, because it gives the kids consistency each day, but leaves Friday mornings free for appointments, errands, playdates, etc.
