After years of competing and touring, Sasha Cohen, the 2006 Olympic silver medalist in figure skating, rarely sets foot in the rink. But she’s watching the Olympics in Pyeongchang with great interest, as she is scheduled to spend a week in South Korea representing the U.S. Olympic Committee later this month. Ms. Cohen graduated from Columbia University in 2016, and currently works for Morgan Stanley as a disruptive change analyst. She has also been contributing to “The Weight of Gold,” a documentary currently in production about the struggle Olympians face as they transition to the real world.
