Dr. Matweychuk Educational and Professional Background

Dr. Matweychuk is a unique practitioner of Cognitive Behavior Therapy as he has worked closely with Dr. Albert Ellis and Dr. Aaron T. Beck, the two founders of cognitive behavior therapy. Dr. Ellis and Dr. Beck have profoundly influenced Dr. Matweychuk’s practical, action-oriented approach to psychotherapy, for which he is very much indebted. Nevertheless, Dr. Matweychuk adheres to the Rational Emotive Behavior Therapy tradition because of, in his view, the distinct advantages of the REBT model of psychotherapy. Dr. Matweychuk writes and lectures on the similarities and critical differences between these two foundational approaches to cognitive behavior therapy.

Dr. Matweychuk first became exposed to Cognitive Behavior Therapy as an undergraduate at the University of Pennsylvania in 1979. There, he worked at the Center for Cognitive Therapy under the direction of Dr. Aaron T. Beck, the originator of Beck’s Cognitive Therapy. He was Dr. Beck’s scribe during weekly group supervision for over a year. He witnessed firsthand and profited from the training Dr. Beck gave his group of psychologists on correctly applying Cognitive Therapy to treating emotional disorders. He was also very much involved in the Center’s research activities at the time on extending Beck’s Cognitive Therapy model to anxiety disorders.

As a doctoral student at Hofstra University, Dr. Matweychuk completed his clinical internship and fellowship at the prestigious Albert Ellis Institute in New York City. For several years, he worked under the direct supervision of Dr. Ellis, the creator of Rational Emotive Behavior Therapy. He became a certified supervisor in Rational Emotive Behavior Therapy.
