It is the aim of Campbell Montessori School to provide and maintain an environment that promotes not only excellence in academics, but also excellence in the social skills necessary for a successful life. Our programs begin with toddler and preschool, which continues through the Kindergarten year. Our elementary program provides developmentally appropriate classrooms for students ages 6 - 9 and 9 - 12. Our program offers Montessori education from 15 months – 12 years, preparing graduates with the confidence in their ability to continue learning throughout their lives.

What is Montessori?

Maria Montessori (1870-1952), the founder of the Montessori method of education, was the first woman recipient of a medical degree in Italy.

After achieving extraordinary results with handicapped and socially deprived children, Montessori was amazed at how normal children responded to the environment she developed.

Montessori is the single largest pedagogy in the world with over 8,000 schools on 6 continents.

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.
