Dartmoor School employs a phenomenal group of individuals who understand the unique setting of personalized education. Our educators have experience working with students who have unique and often highly complex profiles including ADD, learning disabilities, Asperger's, behavioral or pscyhological issues, and giftedness. Educational staff hold a bachelor's degree or higher in their area of expertise, and, regardless of their roles, combine enthusiasm for learning with dedication to the individual needs of our diverse population of students.
