We offer intensive clinic- and home-based treatments for infants, toddlers and school-aged nonverbal children with autism spectrum disorders and/or other developmental disabilities who exhibit severe delays in their overall cognitive, speech/language, social-emotional, motor and adaptive functioning through empirically-supported methods in Applied Behavior Analysis (ABA) such as discrete-trial teaching, pivotal response training, generalized imitation training, echoic/vocal mand training, incidental teaching, and natural environment teaching. In addition, we implement motivational systems (e.g., token economy, choice board) and photographic/written activity schedules across multiple learning environments. Parents are taught through Behavioral Skills Training (BST), which is an empirically-supported procedure that consists of instructions, modeling, rehearsal and feedback. The overall goal is for parents to learn how these methods work to promote socially significant behavior change in important domains.
