This interview with Carl E. Thoresen highlights the experiences, relationships, and ideas that have influenced this pioneering psychologist throughout the past half century. His scholarly work, professional service, teaching, and mentorship have motivated many counseling psychologists to radically expand their areas of inquiry. He was among the first to focus counseling on observable behaviors and to apply psychological science and interventions to physical problems in medical settings. More recently, he has pioneered the study of the interface between spirituality and health. His intellectual vitality, passion for new ideas, and pioneering spirit have earned him the distinction of being included in the Legacies and Traditions series of "The Counseling Psychologist."
