With large classrooms, multi-purpose community space, art room, and library, all housed in 17,000 square feet of newly-renovated space of a historic mill building, every child enjoys an individualized education designed for them to explore and follow their passions. From infancy through preschool, kindergarten, and up through grade six, children develop their inner motivation by working with materials that engage them. Every Montessori material is designed to teach a concept, so children learn as they play with our handpicked materials. All our classrooms have Montessori-trained head teachers, and experienced classroom assistants. Keystone enjoys excellent teacher retention, and has supported hundreds of families, serving children from 3 months to 12 years in age year-round. Visit our school and you'll understand why the founders of Google credit their innovation and creativity to their Montessori education.
