A three-sport athlete, Oksana Masters has represented Team USA at three Paralympic Games in rowing, cross-country skiing, biathlon and cycling. The three-time Paralympic medalist made the successful transition to Nordic skiing after winning bronze in rowing at London 2012 and went on to win Paralympic silver and bronze in cross-country sitting, making her the first U.S. female to win a Paralympic medal in cross-country skiing since 1994. She recently made history again when she became the first American woman to win a Para Nordic skiing world championship title. She captured an unprecedented four gold medals and one bronze at the 2017 world championships in Finsterau, Germany, making her the most successful U.S. woman in championship history. The 28-year-old capped off the season by securing her third consecutive overall women's sitting world cup globe in cross-country and finished third in the world cup overall rankings in biathlon. Masters was born in Khmelnitsky, Ukraine with several radiation-induced birth defects, including tibial hemimelia and was adopted from a Ukrainian orphanage at age seven. With her sights set on completing her medal collection in PyeongChang, the multi-sport phenom will undoubtedly be the one to watch in 2018.
