Mike Levy, MD

Mike Levy, MD (he/him/his) is originally from Albuquerque, New Mexico. He graduated from Stanford University with a degree in Human Biology, where he first fell in love with medicine and teaching.

His work at county hospitals impressed upon him the need for primary care doctors that are skilled at treating substance use disorders as a part of whole person care.
