Our Values:


Joy of Discovery

Dedication to Mastery

Compassionate Love


We envision a time when Ross Montessori School will be an exemplary educational institution and recognized as such all over the world. Educators from all backgrounds will observe and learn from our model, grounded in the Montessori Method. Parents will choose our school over any other with a steadfast belief in the value we create for the children, families, and communities we serve.


Our children will be immersed in the joy of discovery. Programming will be enriched with art, music, and drama through all the seasons. Students will actively participate in community service projects and conservation programs, and every child will emerge a creative and competent problem solver.


We will send citizens into the world who have a profound impact on their communities. They will face adversity and challenge with humility, grace, and compassion. They will inspire others to better the Earth and its inhabitants. All who know them will be better for it for generations into the future.
