In the fall of 2000 he was an adjunct professor at the University of Arizona Department of Psychology teaching a course he developed on transpersonal psychotherapy entitled “The Psychology of Spirituality and Religion”.

His studies of transpersonal psychology began in the early 1970’s, as inspired by the California Institute For Transpersonal Psychology, and he received his Masters of Social Work degree from Arizona State University in 1984. He has studied gestalt therapy, bioenergetic analysis, ego psychology, object-relations theory, gestalt family therapy, short-term counseling methods and transpersonal psychology. He developed a model of clinical supervision that he has applied in a number of behavioral health settings. He attends a clinical supervision group that began in 1982, and has presented several times a 12-hour training in the clinical supervision of psychotherapy that links the literature on the topic with real world cases and recent changes State licensing laws.

His work with organizations began in behavioral-health firms and has now been accomplished in diverse professional settings: hospitals, law firms, retail organizations, and high-tech computer manufacturing industries.
