Meet the Doctor
Dr. Ahn is a medical oncology specialist at Keck Medicine of USC.
“Because I love soccer so much, I wanted to become a soccer team doctor. I thought the job would allow me to watch the game from the bench and get to personally know the players, so I seriously considered majoring in sports medicine.”
