Programs and Services:
Birchtree’s year-round day school for students with autism provides seamless 12-month programming based on the principles of applied behavior analysis (ABA). Birchtree’s Board Certified Behavior Analysts, Special Educators, Speech-Language Pathologists, and Occupational Therapists tailor instruction to each student’s strengths, challenges, and Individualized Education Plan. Direct support staff, including Registered Behavior Technicians, are highly trained in ABA and closely supervised by BCBAs while delivering individualized programming one-on-one and in small groups.
Instructional areas include standards-based academics, communication, social skills, self-care, hygiene, mobility, fitness, behavior, self-regulation, vocational skills, and independent-living skills. Students participate in a wide range of community-based activities to promote independence across various settings.
Additional Information:
Our Outreach team helps individuals with autism and other diverse abilities, ages three and up, to succeed in their local public schools, at home, and in their communities. Our Outreach BCBAs offer system-wide consultation, educational and behavioral consultation, professional development workshops, assessments, and program evaluations to benefit individuals with autism, ADHD, developmental delays and disabilities, or more broad behavioral needs. We can help with school avoidance, trauma history, attendance issues, medical appointments, and more. BCBA consultation and services are offered throughout New England. Direct ABA therapy in public school settings by our Clinical Instructors/RBTs may also be available; these services are typically offered in southern New Hampshire, southern Maine, and northern Massachusetts. Please call Stephanie Morin at Birchtree to inquire about Outreach service delivery.
History and Philosophy:
Birchtree is a nonprofit organization established in 2002. Its mission is to support individuals with autism and other diverse abilities by providing personalized education and outreach programs that promote inclusion, independence, and holistic growth.
