In 1988, Oneness-Family School (OFS) Founder and Head of Upper School Andrew Kutt set out to create a school built upon Maria Montessori’s philosophy — where the center of the educational process is the student. Three decades later, what began with 10 students in a public school library is now a global family with thousands of alumni students following their dreams across the planet.

Oneness-Family Montessori School, which serves students in preschool through high school, and is home to students from more than 60 countries, is a family-focused school that encourages a strong partnership between school and home. Its learning program combines a research-based Montessori curriculum with an emphasis on well-being, community, character and lifelong learning.
