Bozeman Summit School is a member of the American Montessori Society (AMS), the foremost advocate for quality Montessori education. All lead teachers have received their Montessori training from an accredited AMS training center. The American Montessori Society was founded in 1960 by Nancy Rambusch in response to the overwhelming public demand for more information regarding Montessori education.
