Amanda Thompson, BCBA

Amanda Thompson

Director of Specialized Clinical Services

Amanda serves as the Director of Specialized Clinical Services, bringing more than 20 years of experience in the field of Applied Behavior Analysis (ABA) and over 10 years as a Board-Certified Behavior Analyst (BCBA) and Qualified Behavior Modification Professional (QBMP). Her career has been rooted in a commitment to improving quality of life through thoughtful, person-centered clinical practices, strong collaboration, and meaningful relationships with the individuals and teams she supports.

Her clinical background spans the lifespan and includes early intervention, focused ABA services, community-based programming, and the supervision and development of RBTs, BCaBAs, and behavioral consultants. After more than 16 years working primarily with children on the autism spectrum, she made a purposeful transition into adult services, expanding her work to individuals with developmental disabilities, complex behavioral needs, and co-occurring mental health challenges.

Her experience includes providing and overseeing behavioral services in highly specialized settings, including Enhanced Behavioral Support Homes and Community Crisis Homes. She has supported individuals with complex clinical needs while also leading and mentoring behavioral teams, developing consultants, and promoting strong clinical decision-making across programs. This combination of direct clinical experience and leadership gives her a practical, well-rounded perspective on delivering high-quality services in challenging and highly individualized environments.

As Director of Specialized Clinical Services, she brings that experience into a broader leadership role focused on strengthening specialized clinical programming, supporting and developing consultants, promoting clinical integrity, and fostering collaborative, person-centered services. She values strong clinical judgment and ethical practice, but equally values the relationships behind the work—believing that the best outcomes happen when clients, staff, consultants, families, and interdisciplinary teams feel heard, respected, and invested in the process.

At the heart of her clinical philosophy is the belief that meaningful change does not always have to be big. Sometimes, small and intentional changes can have the greatest impact on a person's independence, happiness, and overall quality of life. Her personal motto reflects that philosophy: “Saving the world with ABA, one person at a time.”

Outside of work, Amanda enjoys spending time with her family, walking her wonderfully wild German Shorthaired Pointer, and getting lost in a good book. She loves camping adventures in the family travel trailer and will never turn down an opportunity for a trip to Disneyland.
