Kendra McDonald, MA, BCBA 
Director of Clinical Services


As a mother of a son with autism, the confusing journey through the therapy and educational system is familiar to me. When my son Cannon was first diagnosed, I was overwhelmed, scared and lost. I had a lot of questions: How was I going to choose from the variety of therapeutic options? How would I know which therapy would work? Through a lot of research, and much trial and error, I discovered that ABA therapy (a way of using things that motivate your child to learn to communicate, behave, and learn) made a remarkable difference in Cannon’s life. He finally started to communicate with purpose, and his challenging behaviors began to diminish. I saw how he could meet goals and become independent. ABA gave my family and I hope!

After spending several years providing in-home therapy for Cannon, I knew I wanted to become a therapist and help children with the same needs. I started working for The Arc of Loudoun as an ABA Therapist for The Aurora School (a private day school for students with disabilities) and Open Door Learning Center (a preschool for students with and without disabilities). I later became Director of Clinical Services for the entire Arc campus. Throughout my twelve years of working as a therapist, I’ve seen astronomical success in students who went from not communicating at all– to being able to read text, sign words, and talk vocally. These students’ lives were changing– all from ABA therapy!

Although both Aurora and ODLC provide exceptional services for children with disabilities, I couldn’t help but think about all the children with special needs who may need intensive therapy, but didn’t have the opportunity to attend these schools. I know as a parent, I would’ve loved for something like Aurora Behavior Clinic to exist when Cannon was growing up. At Aurora Behavior Clinic our goal is to help your child improve their communication, behavior, social, and academic skills through intensive ABA therapy. We also want to help you, as a parent, by offering support, guidance, and access to professional trainings.  After seeing the incredible results from our clinic, you will have the same hope I did!
