ABA Therapy


Applied Behavior Analysis (ABA) Therapy is a highly effective approach to enhancing socially significant behaviors and limiting behaviors that interfere with learning.  In multiple studies, ABA therapy has been shown to significantly improve children’s cognitive and language skills, as well as adaptive behaviors. Through frequent data analysis and environmental interventions, our Board Certified Behavior Analysts (BCBAs) and staff therapists work with you and your child to increase independence and success through programming that caters to your child’s needs. 

ABA Therapy is the Most Effective Treatment for ASD

Did you Know?  

High quality ABA intervention can do more than enhance socially significant behaviors, it can improve brain function.  Research has shown that ABA Therapy not only improves social skills, but also brain responses to social cues.

Being nonverbal at age 4 does NOT mean children will never speak.  With ABA Therapy, most will learn to speak, and over half will speak fluently. Building language skills is a major focus of ABA Therapy.

Though autism is considered to be life long, with ABA Therapy, some children make so much progress that they lose the core symptoms and no longer meet the diagnostic criteria for autism.  This is called “optimal outcome”, and research is showing that high quality, early intervention using ABA Therapy is key.


For EPIC Changes We


Through observations, interviews, & assessments our Board Certified Behavior Analysts (BCBAs) determine areas of your child’s repertoire to strengthen.


We design a custom program for your child based on his or her needs and your shared goals using the latest research and best practices.


Working one-on-one with your child, our therapists implement the program.  Parent training is provided so that you can help maximize the program’s effect.


As your child’s behavior changes, the program is refined to ensure continued progress.
