Tom Szabo, PhD, BCBA-D, is a faculty member in the hybrid master's degree program for Professional Behavior Analysis at the Florida Institute of Technology, an internationally recognized acceptance and commitment therapy (ACT) trainer, a practicing board certified behavior analyst, and a graduate of the University of Nevada, Reno, where he studied under Steven C. Hayes and W. Larry Williams.

Over the last decade, Szabo has focused his practice on teaching people ways to ignite behavioral flexibility in their personal lives and with others in clinical practice, schools, boardrooms, shop floors, and community centers. He is particularly interested in teaching people ways to use the "psyflex model" to support individuals with high functioning autism and their families. With the Commit & Act Foundation, Szabo has trained therapists in Sierra Leone working with individuals who've committed acts of gender-based violence and he is currently conducting funded research on ways to reduce intra-familial violence. With his students, Szabo investigates ACT training and clinical RFT. He has published empirical and conceptual papers, as well as several book chapters.
