Green Tree School

A nonprofit organization

Green Tree School & Services (GTSS) is a nonprofit, state-licensed agency that provides education, therapeutic and clinical support to children ages 5-21 with Autism Spectrum Disorder and Severe Emotional Disability. GTSS only serves children whose disabilities are such that they are unable to succeed in a school- based special education program or participate in out of school activities. Rates of both diagnosis are growing, with 1 in 68 children currently affected by Autism and 1 in 78 children affected by Emotional Disability.

GTSS’ philosophy is rooted in the belief that every child should have the opportunity to learn the academic, social, emotional, and vocational and life skills they need to achieve resiliency and succeed in their learning, living and working environments. GTSS has worked with children and young adults with special needs since 1957, marking over a half century of Transforming Lives and Impacting Communities.

As an Approved Private School (APS), Green Tree School & Services provides full-time, out-of-district placement, for students with the emotional support or autistic support needs. GTSS supports the development of the whole child, by providing speech therapy, occupational therapy, school counseling, and nursing services, in addition to our special education classrooms. Students are provided well-rounded education with community integration, service learning, art, music, and more. GTSS strives to help students return to their home community schools and prepare them for a life after school by providing vocational training and job readiness training.

To discover, develop and deliver opportunities for children with unique challenges and abilities to achieve their full potential.
