About the Practice
My Team
John C. Tanner, MD
Dr. John C. Tanner grew up in the suburbs of Chicago and earned his undergraduate degree in mechanical engineering from Stanford University. He worked as an engineer designing surgical tools for five years, which led to his interest in medicine and surgery. Dr. Tanner attended the University of Southern California for medical school, then returned to the Midwest for residency at Michigan State University. Orthopedic surgery was a natural fit with his engineering background and after completing his orthopedic Foot and Ankle Fellowship, he practiced in Michigan before moving to Minnesota to be closer to his wife’s family.
Dr. Tanner has been with Twin Cities Orthopedics for over 10 years, and is proud to be part of such a high-quality organization. His clinical practice focuses on the lower leg, with specialty care for the foot and ankle. Dr. Tanner is faculty for the TCO Foot and Ankle Fellowship and the Team Doctor for Park Center High School. He has over 12 years of experience taking Level 1 trauma call.
In Dr. Tanner’s time away from work, he enjoys being a husband and father. His wife, Elena, is also a physician, working as an OB/GYN at Abbott hospital. They have two sets of twins, so their family is extremely busy but blessed with an amazingly supportive extended family to make it all work. In addition to spending time with his wife and kids, he enjoys singing, cooking, playing guitar, coaching soccer for Kickers FC, racquetball, golf, and snowboarding.
