"Keystone Montessori is exactly the experience I hoped for. Not only is it AMI certified, the teachers are so compassionate and supportive of the children. Right now the children are really loving their gardens and eating the fruits of their labors. I know the children are getting the attention they need to be a productive humans in society."

"My children are happy and thriving in school. There has always been a great sense of family and community at Keystone that is not easy to find. I feel confident that the guides and staff have the childrens’ best interests in mind in all decisions they make."

"This school fosters independence, social learning, and most of all, encourages the flame of the love of learning. So often in traditional school settings the rigid nature of the curriculum and the over-focus on "points" kills children's intrinsic motivation to learn, so that when they get to college the light in their eyes has gone out and they care only about grades. I'm so happy that this wonderful school exists, and that it goes through the upper levels. Montessori is not just for preschool--it's for all ages."

"We love the supportive learning environment for the children. There is a focus on instilling a love of learning in the children. The school is much more than just a place for teaching and learning."

Updates From Ms. Laura & Mr. Stefan

 

We would like to wish our Keystone Families, students, and staff a well-deserved summer break! As our 2023/24 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. Our community is a constant source of pride, and we are grateful for your continued support.

This year brought an abundance of joy and has left me with a grateful heart as I look back on the memories made. We were blessed with your generosity at the Fall Festival, during the Sustaining Fund, and throughout the year. It was a joy to witness the community come together for many class celebrations and events, including the Peace Program, class plays, potluck dinners, community meetings, and Movie Night this spring. Our students made memories throughout the school year with their class activities, going outs, and fabulous trips as we closed the year. The Keystone community seems to bring out the very best in all of us.

Please take some time for rest and rejuvenation this summer. 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                            Stefan Linder
Head of School                          Associate Head of School
