Dr. Sara Johnson graduated from Westmont College in 2005 with a B.S. in Biology. She attended the Keck School of Medicine of the University of Southern California, where she earned her M.D. in 2010. Dr. Johnson is triple board certified in Emergency Medicine, Preventive Medicine & Public Health, and Lifestyle Medicine. Her work as an emergency physician in one of the nation’s largest safety-net hospitals allowed her to experience the epidemic of chronic disease we face in our country as well as to learn how ineffective our standard treatments for these diseases often are. This sparked a pursuit of more effective, evidence-based therapies for chronic diseases, through which she discovered the fields of preventive medicine and lifestyle medicine. She is one of only a handful of physicians in the nation to have completed a Lifestyle Medicine Intensivist Fellowship. She is active in education and leadership through her role as the associate program director and faculty editor of the Lifestyle Medicine Residency Curriculum, a joint project of the American College of Lifestyle Medicine and Loma Linda University.  Dr. Johnson furthers her research interests with her work in knowledge translation, taking the research on lifestyle medicine and applying it in the clinical arena.
