"We came to Keystone for the authentic Montessori education. We fell in love with Keystone when we realized it was more than just a school, it was a community."

"Once my husband and I visited Keystone Montessori, we stopped looking. We have now been a part of the school for six years. It takes a village to raise a child, and Keystone is the living example of a community working together for the future of each child."

The teachers, staff, and parent community all work together to ensure our children receive an outstanding education that focuses not only on academics, but also on grace, courtesy, and respect for their community."

From Ms. Laura's Desk

We would like to wish our Keystone Families, students, and staff a wonderful summer break! As our 2020-21 school year draws to a close, we reflect on our time together and I am amazed at how quickly it seems to have passed us by. The year was a testament to our Montessori resourcefulness, resilience, and passion. As a community, we met each challenge together and watched in awe as our students excelled in their exploration and discovery both in the classroom and while learning at home.

Please enjoy some well-deserved rest and rejuvenation this summer. Each member of our community has gone above and beyond expectation to ensure a successful year amid the challenges we have faced, and my wish for each of you is peace and calm. The administration team at Keystone will continue to work for the benefit of our students over the next two months, and we look forward to welcoming everyone back to campus in August!

Please accept our gratitude, good wishes, and thanks for a wonderful school year.

In Health and Peace,

Laura Hertzler
Head of School
