Our History

Campbell Montessori School was founded in June 1989 to bring Montessori education to the St. Charles area.

Opening as St. Charles Montessori Academy under the sponsorship of Greater Missouri Builders, Inc., the school was housed in a new two-classroom building at 1250 Hawks Nest Drive in St. Charles. In the fall of 1992, parents asked about the possibility of having an elementary school.
