Dr. Joseph E. Morrow has received his Ph.D. in experimental Psychology in 1965 from Washington State University. He has taught at the California State University, Fullerton; Indiana University, South Bend (where he was department chair); and California State University, Sacramento, where he was Professor of Psychology and Behavior Analysis (Emeritus). Dr. Morrow was a pioneer in the academic development of Behavior Analysis in California, creating one of the first courses in 1966. He has published several papers on behavioral psychology and his first publication on the behavioral treatment of autism was in 1966. His academic career resulted in many awards, culminating in the Livingston Lecture at Cal-State Sacramento in 2002. “This award recognizes a sustained and unique contribution to the campus community in providing intellectual leadership and has important significance to the life of this university.”
Dr. Morrow has been an active member of the behavioral community and a member of The Association for Behavior Analysis, International (ABAI) since 1974. In 2006, he was given an award from that organization for “Outstanding Contributions to the International Dissemination of Behavior Analysis”.

Brenda Terzich-Garland, M.A., BCBA
CEO and Co-Founder
Brenda Terzich-Garland is the President and CEO of Applied Behavior Consultants, Inc. She co-founded ABC with Dr. Joseph Morrow and has been instrumental in developing ABC’s clinical approach and international expansion. In 2020, she authored “The R.E.A.L. Model™, Rethinking Generalization” (Different Roads to Learning, New York), which has become the foundation for all of ABC’s clinical programming worldwide.
Her groundbreaking work on the R.E.A.L. (Recreating Environments to Accelerate Learning) methodology, developed in 1996, has transformed how ABA therapy addresses generalization of skills. This approach ensures that skills learned in therapy transfer effectively to real-world environments, enabling children to connect meaningfully with their families and communities.
Under her leadership, ABC has expanded internationally across four continents, bringing cutting-edge ABA therapy to families in Europe, Asia, and Africa. She continues to advance the clinical treatment of autism globally through consultation, training, and the establishment of ABA programs worldwide.

Our Therapy Team
Our Behavior Therapy team are the heart of our daily therapy sessions. Each therapist is trained with our global training system, and supervised through Lead therapists and Behavior Analysts to deliver cutting-edge ABA therapy with care and compassion.
Robust Training
All therapists undergo theoretical and hands-on training on ABA, as well as supervision from Lead therapists in order to ensure quality program implementation.
Dual-Level Supervision
Our therapy team undergoes ongoing supervision in two vectors. Firstly, there is supervision from a Lead Therapist to ensure that programs are implemented in line with target. Secondly, there is supervision from a Behavior Analyst, to ensure that the child’s lesson design is in line with learning capability.
BCBA Supervision
Every child’s program is overseen by a Behavior Analyst, who is supervised by a Board Certified Behavior Analyst to ensure all programs are in line with ABA principles and ABC Center guidelines.
Compassionate Care
We select team members who demonstrate not just technical skills, but genuine passion for working with children and families.
