Clinical Director

Jason Lewis, MS, BCBA

 Jason graduated from Michigan State University in 2002 with a degree in Criminal Justice.  Following graduation he moved back to his home state of Pennsylvania and discovered Applied Behavior Analysis (ABA) by working with children diagnosed with Autism. While working with kids in the Behavioral Health Rehabilitation Services (BHRS) in the state of Pennsylvania, he learned that Behavior Specialists who supervised him, did not produce much behavior change for those kids with whom he worked. Convinced that there was a better system to teach skills to kids diagnosed with Autism, Jason discovered the field of ABA and its successful work with kids in this population.

 Upon discovering the field of ABA, Jason enrolled in the Graduate, Criminal Justice program at Saint Joseph’s University in Philadelphia, PA.  Here, Jason learned the principles of ABA and earned a Master’s degree in Criminal Justice with a concentration in ABA.  Upon completion of his Master’s degree in 2005, Jason became a Behavior Specialist in the BHRS system to begin implementing behavioral interventions for kids diagnosed with Autism.

 Jason did in-home consultations in the BHRS system for about 4 years before moving to a new position at center created to provide services for kids and adults diagnosed with Autism.  The center, known as the Autism Resource and Community Hub of Lehigh Valley (ARCH of LV), located in Allentown, Pennsylvania, provided different types of services; however, Jason oversaw the after-school and summer camp programs.  In this position, Jason designed programs, based on the principles of ABA, in order to teach social and daily living skills to all clients receiving services.  Jason worked in this position for more than 5 years before moving to Florida to further pursue his long-term goals.

 Currently, Jason is attending the Florida Institute of Technology at the Orlando campus.  There, he is pursuing a second Master’s degree in ABA in order to fulfill his dreams of earning a Ph.D. in ABA.  His interests include effective teaching interventions and language development and how it applies to social development.  Outside of school and work, he enjoys music, particularly writing and playing songs on his guitar and studying music theory, exercising and enjoying the Florida weather.
