Michelle Bouchard, BCBA

Clinical Director 

My passion is to provide children and their families the very best treatment possible. I believe treatment should be individualized and specifically designed for each client; not a cookie-cutter formula for them to follow. I enjoy every aspect of my job and feel so fortunate that I get to go to work with children and their families. I have been working in the field for over 16 years, and have experience working in families’ homes, within the school district, in clinics, and research settings. 

I received my Bachelor’s in Science from Western Michigan University, where I was introduced to the field. My practicum was completed at a school designed specifically for children with autism, where I fell in love with the work, and found my niche. I then pursued my Master’s in School Psychology and became a Board-Certified Behavior Analyst.

I worked at the University of California, San Diego (UCSD) doing research on early intervention with children with autism; this was part of the autism intervention research program (AIRP) Autism Center of Excellence, under Dr. Laura Schreibman and Dr. Aubyn Stahmer. I was trained in Pivotal Response Training by Dr. Schreibman (the co-developer of PRT and a leading expert in treatment for children with autism) and Dr. Stahmer (developer of Classroom Pivotal Response Teaching [CPRT]). Additionally, I was trained in how to teach social communication to children with autism developed by Dr. Brooke Ingersoll and Anna Dvortcsak. I am also well versed in Naturalistic and Developmental Behavior interventions. 

Interventions Trained In:

  • Pivotal Response Treatment (PRT)
  • Early Intervention Developmental Model
  • Positive Behavior Supports
  • Picture Exchange Communication (PECS)
  • Natural Environment Teaching (NET)
  • Verbal Behavior 
  • Social Communication
  • Parent Training

I look forward to an opportunity to work with you.

Office Manager

Registered Behavior Technician 

I am committed to making a difference in the lives of children, working with Believing In Change allows me to do so every day. My positions at Believing In Change are Office Manager and Registered Behavior Technician. I am extremely lucky to be a part of the administrative side and the clinical side of ABA therapy, this allows me to go one step further in helping our kids! 

As a Registered Behavior Technician, working one on one with our kiddos and their families motivates me every single day to reach their goals and make a positive impact on their lives. 

I am a college student working towards a bachelor’s degree in Sociology to eventually become a licensed clinical social worker. I look forward to the opportunity to work with you.
