Claire Clark is an associate professor (emeritus) at the University of Utah School of Medicine (UUSOM) and a practicing clinical psychologist. She is a longtime practitioner of Bon Buddhism and student of Tenzin Wangyal Rinpoche. Her work at UUSOM focused on teaching medical students and residents in the art of medicine, doctor/patient relationship, and humanism in medicine. Her social medicine classes integrated students into the community, where they learned the crucial impact of psychosocial factors on the health and illness of their patient populations. For 15 years she served as assistant dean for student advising and counseling, providing psychotherapy and support to medical students and their families.

She is a member of both the 3 Doors and Ligmincha research teams who are studying the impact of longitudinal and short-term meditation programs.
