Surrey Place Centre/TRE-ADD program is a comprehensive day treatment program that provides services for children and youth with autism and related developmental disorders and their families. Our primary focus is on preparing the child/youth with multiple and complex needs to be successful in a less intensive programmed educational setting, and to enhance the ability of the family to support him/her. Our treatment approach is individualized, comprehensive and multi-disciplinary with an enhanced focus on the application of Applied Behavior Analysis (ABA) procedures and principles.
