To become a sports medicine doctor, you have to go to college first and then medical school. You'll need to take certain courses in biology and chemistry as prerequisites for med school and you'll need a GPA of 3.6 or better to get into med school. Quite a few of the colleges in Ohio can provide you with the necessary science courses -- Ohio State, Ohio U., Case Western Reserve, U. Cincinnati, Miami U., Oberlin, Wooster, Kenyon and Denison, among others.
