Meet Dr. John Hammerstein!

Dr. John Hammerstein, a 1996 graduate of Indiana University and a later graduate of IU’s School of Medicine, played football for Indiana University. A starter for the final three years on the team, Hammerstein was voted team captain his senior year.

Dr. Hammerstein recently completed an orthopedic sports medicine fellowship at the esteemed Andrew’s Research and Education Foundation in Gulf Breeze, Florida. He began the fellowship to broaden his orthopedics practice by gaining experience in sports medicine. While there, he actively participated in team coverage of Division 1 football with the Auburn Tigers and oversaw local high school athletic teams.

He’s glad to be coming back to Indiana this year, “after growing up in small town America I have wanted to practice in a place like Greene County where patients are also your neighbors. I am looking forward to being involved in the health and well-being of the community.” To find out more about the Andrew’s Research and Education Foundation click here.
