Her competitive foundation was shaped by the Hawaii High School Athletic Association, a program in which she ultimately earned three individual championships, signaling her status as one of the most accomplished young players in the state.
Her first national spotlight came at age 13, when she qualified for the 2011 U.S. Women’s Open and became the youngest golfer in the field.
