“At ABC Montessori, the principles of integrity, co-operation, responsibility, and respect are modeled by teachers, emulated by students, and practiced by all. While other schools are exclusive, not recognizing the cultural and religious celebrations of its student body, ABC Montessori is inclusive in acknowledging its cultural and religious diversity. Our daughter has learned tolerance, respect, and understanding”

– Mary Jo S. – Parent

“Seven years ago we decided to enroll our young daughter at ABC Montessori School, and as we look back, it is absolutely one of the best decisions we have ever made.”

– Vincent and Alice L


Committed to academic excellence, personal growth and the most fulfilling educational experience.
