From Ms. Laura's Desk


We would like to wish our Keystone Families, students, and staff a well-deserved summer break! As our 2021-22 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.

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
Head of School
