November seems a perfect time to pause and express gratitude. All of us at Keystone are grateful to Dr. Montessori, and the vision she shared with the world of a better way for our children. In her shadow, thousands of guides and parents across the globe are committed to asking more of ourselves in the name of the Child. 

I once read, “Gratitude is happiness doubled by wonder”. That is a perfect reflection of what we have experienced in this first portion of the year at Keystone. Every day, I am moved and inspired by what I see. I marvel at the incredible devotion of our staff and their unique ability to guide and inspire our children. I celebrate the amazing support of our parents and community.

I believe Keystone’s success is built on a foundation made of the combined efforts of those of us in the school building and the families who support us. Each day, dedicated guides and staff nurture a culture of fairness, love, and caring. The goal is continue to provide an exceptional learning environment for our students and families. The support and commitment of our Keystone community is humbling in so many ways. The small moments of a quick hello while you pick up and drop off your student, time spent attending observations and conferences, the hours volunteering to make our special events a success all combine and leave our hearts full. 

In this season of thanks, please know each of you are appreciated beyond measure.
