Keystone Montessori School was established in March 1994, as the result of the deep commitment of Victoria Shea, who in partnership with Montessori parents and teachers in the Oak Park/River Forest area, wished to provide an authentic Montessori education for children ages four months to adolescence.
Keystone is incorporated as a not-for-profit parent-teacher initiative and meets the standards established by the Association Montessori International (AMI).
