She was on the U.S. gold medal team in the Pan American Games in 1979, riding Val de Loire. She qualified for the 1980 Olympics, but did not compete due to the U.S. Olympic Committee's boycott of the 1980 Summer Olympics in Moscow, Russia. She was one of 461 athletes to receive a Congressional Gold Medal instead. She also won a bronze medal in the individual jumping category on Calypso at the Alternate Olympics. She qualified for the Olympics again four years later in 1984, and helped win the first team gold for the U.S. in Olympic Show Jumping, again riding Calypso. In 1980 she placed second in the World Cup on Calypso, and at the 1982 World Cup, she won. She also rode Calypso to help the U.S. team win the Nations Cup and the World Cup in 1983. She won the show jumping triple crown on Calypso, becoming one of two riders to achieve that honor, as well as the only horse/rider team ever to do it.
