For the past 11 years, Mountainside has been providing Montessori education for children from Fauquier, Prince William, and Culpeper counties. In 2010, our mission expanded to include sustainable agriculture, environmental stewardship, and free play in nature. As our purpose grew, so did our school community. We are about to open a new campus on Belvoir Road in Marshall. This 10-acre site will allow us to serve children from birth through ninth grade, as well as offer programs to the community at large.
