Dr. DiTomasso graduated with a BA in psychology magna cum laude in 1973 from La Salle
University and then pursued and completed an MS degree in general-experimental psychology
from Villanova University in 1975, where he was the recipient of a research assistantship.
This was a rigorous program that provided a solid foundation in scientific psychology
and, later, an empirical focus for his clinical work. It was at Villanova where Dr.
DiTomasso took his first course in Behavior Therapy and discovered an area of study
devoted exclusively to helping people through the use of empirically-derived techniques
based upon learning principles - a perfect match for his interests.
The next year he entered the PhD program in professional-scientific psychology at
the University of Pennsylvania and over the next four years he refined his interest
in behavior therapy, cognitive therapy, and research methods. While at Penn he was
awarded a teaching fellowship and was mentored in the art of teaching. Subsequently,
he attended the June Institute in Behavior Therapy and completed an internship under
the direction of Joseph Wolpe, MD at the Behavior Therapy Unit, Eastern Pennsylvania
Psychiatric Institute, Temple University School of Medicine, Department of Psychiatry.
Upon graduation from the University of Pennsylvania, he was awarded the William E.
Arnold Dean's Award in recognition of outstanding leadership and scholarship. He later
obtained postdoctoral training and supervision in cognitive-behavioral therapy and
family therapy and completed a certificate in cognitive therapy under the direction
of Arthur Freeman, EdD, ABPP.
Dr. DiTomasso's major areas of interest are cognitive-behavioral assessment, therapy,
and consultation, anxiety and anxiety-related disorders, primary care psychology,
patient non-adherence, developing assessment instruments for health risk behaviors,
