Visit Us

Our campus is located on 11 acres of former farmland in Stratham, NH. The indoor and outdoor environment is designed to facilitate presentation of Montessori curriculum. The best way to experience the inherent love of learning that exudes from our students is to come in and tour the school and schedule an observation in the classroom. Tours and observations are by appointment only. Please call us at 603-772-4349 to schedule.
