Andrew Thomas Weil (/waɪl/, born June 8, 1942) is an American celebrity doctor who is a physician, author, spokesperson, and broadly described "guru" of the alternative medical brands: holistic health and integrative medicine, whose name also constitutes an emerging brand of healthcare services and products in these fields.
Weil became interested in the ideas and practices of complementary and alternative medicine, and went on to play a seminal role in codifying and establishing the emerging field of integrative medicine, which aims to combine alternative medicine, conventional evidence-based medicine, and other practices into a higher-order "system of systems" to address human healing via action in multiple "dimensions" (biological, psychological, sociological, and spiritual). As of 2015, Weil serves as an academician at the University of Arizona College of Medicine, where he is Lovell-Jones Professor of Integrative Rheumatology, Clinical Professor of Medicine, and Professor of Public Health. In 1994, Weil founded and has since directed the Arizona Center for Integrative Medicine. He served as founding editor of a seminal OUP series offering medical best-practice methods alongside yet-to-be-proven ones, the Weil Integrative Medicine Library (2009-2015), which includes specialty volumes in oncology, cardiology, rheumatology, pediatrics, psychology, and other specialties.
