RMS is a private school that has educated children for nearly 50 years starting in a private home in 1968 with only 12 children. Today, the school is situated on a beautiful 15 acre campus where a complete Montessori education is offered for children from 18 months through the eighth grade. For students in grades 6, 7, and 8, RMS is both a Montessori School and an authorized International Baccalaureate (IB) World School. The growth and success of RMS could not have happened without our highly qualified staff and the support of our community. Great pride is taken in the fact that the Montessori philosophy has been embraced and continues to thrive at RMS and the greater Rochester area.
