 26-year-old Ron Carno of Maplewood, New Jersey in his first Olympics, preparing to swim in the 200-meter individual medley. The undescribable feeling that, wow, I finally made it and here I am representing the United States. As Ron marched to the opening ceremony, his father, Peter, minutes after catching his son's eye and waving to him, suffered a heart attack and died at the Olympic Stadium. When my father tragically passed away at the opening ceremony, that was the darkest moment of my life. Seeing how meaningful it was for the physician to help my own parents, that was the catalyst for my interest in medicine. Something has taught me the ability to deal with adverse circumstances. Karen Gillian, she's a world-class diver and when I learned about her disc herniation and her lower back, it was really something that I thought I could help her with. It really paid off because now she's back in training and she's doing great.
