Dr. Lorna Smith Benjamin is the founder and creator of Interpersonal Reconstructive Therapy and Structural Analysis of Social Behavior. She is Professor Emerita of Psychology at the University of Utah and Founder of the Interpersonal Reconstructive Therapy Clinic at the University of Utah Neuropsychiatric Institute (UNI).

Dr. Critchfield studied under Lorna at the University of Utah and worked closely together for almost 2 decades. The ongoing development of Lorna's life's work, SASB and IRT, is central to the Institute's mission.

Dr. Benjamin is now in retirement and is not formally or directly affiliated with the IRT Institute. Lorna's wisdom and compassion continues to help those who have needed more than standard treatment to heal.
