Gwen has worked with children with a variety of special needs for over a decade. Although she is often asked whether she finds this career difficult or frustrating, her answer is always “No.” She finds working with her clients to be fascinating, challenging, and rewarding.  She loves watching the children gain new skills and confidence in themselves.  Gwen also enjoys working with families to increase their ability to understand and engage in positive interactions with their children.

As a behavior therapist and consultant for the past 15 years Gwen has had extensive experience training and supervising teams of clinicians working with children with Autism Spectrum Disorder (ASD), developmental disabilities, Attention Deficit Hyperactivity Disorder (ADHD), and learning disabilities. She has provided expert advice for Individualized Education Plan (IEP) meetings between school districts & parents. In order to determine levels of functioning and to appropriately create individualized treatment plans for her clients, Gwen has experience administering developmental and educational assessments.

Over the years, Gwen has learned that all of her clients respond uniquely to intervention.  In order to provide the best intervention, she has learned about many different approaches.  As Gwen meets each new client, she works to develop an individualized treatment plan, rooted in evidence-based intervention, that meets his or her unique needs.
