What are the qualifications for ABA therapists?
ABA therapists are typically BCBAs or RBTs with specific training and certification in behavior analysis.
ABA therapists typically hold specific qualifications to ensure they are equipped to provide effective therapy. In Colorado and Texas, many ABA therapists are Board Certified Behavior Analysts (BCBAs) or Registered Behavior Technicians (RBTs). BCBAs must complete a master's degree in behavior analysis or a related field, followed by supervised experience and passing a certification exam. This rigorous training ensures they have the knowledge and skills necessary to design and oversee individualized treatment plans. RBTs, on the other hand, are required to complete a training program and pass a competency assessment. While RBTs work under the supervision of BCBAs, they play a crucial role in implementing therapy strategies. Families should inquire about the qualifications and experience of their chosen ABA therapists to ensure they receive high-quality care tailored to their child's needs.

I’ve been working in the field of behavior analysis for over a decade, supporting children and families across clinic, home, and school environments. I earned my Master of Arts in Teaching with a focus on Applied Behavior Analysis from National University, and I’ve held leadership roles in regional and remote clinical settings.
In May 2025, I founded Tiny Wonders ABA to bring individualized, compassionate care to families in the Portland area. I am passionate about parent education, team collaboration, and building programs that help kids thrive in their natural environments. My work is grounded in both data and empathy, and I strive to ensure each child I support is seen, heard, and empowered.
