Over 10 years ago, what began as the radical, heartfelt response of six teachers to serve students with autism spectrum disorder (ASD) and developmental disabilities, has grown into one of the top schools for autism in the United States. Using Applied Behavior Analysis (ABA), an evidence-based science, we identify what each student needs to create an independent and fulfilling life. These might include social skills, communication and language, academics, daily living and community skills, vocational skills and more. By providing our students with structured environments, using teaching strategies based on behavioral intervention, and using data to inform programming, our nationally recognized approach has achieved superior results.


We are making a real difference in the lives of students with ASD and their families. Our programs serve children from age 2 to 21, through our integrated preschool program at the Joshua Early Childhood Center, and our school-age and transition programs at our Denver and Boulder campuses.
