Autism Behavior Services, Inc. (ABSI) is proud to announce we are now providing Applied Behavior Analysis (ABA) in Pennsylvania. The company was founded in California and is pleased to announce its expansion to the East Coast. ABSI specializes in providing researched based ABA treatment in both 1:1 and social group settings. Dr. Rosa Patterson developed Let’s Learn about Friends and Feelings (Let’s L.A.F.F),a social group that promotes the social-emotional and behavioral growth of individuals affected by an autism spectrum disorder.

Our Radnor office is coordinated by Carolyn Giardini. She has over ten years of experience working under Dr. Rosa Patterson. She has a passion for working with children and making a difference in their lives. Carolyn has worked with countless families and has been recognized numerous times for her hard work and dedication.
