Nurys Sebey began playing volleyball in the early 1960s, competing in local and regional competitions in Cuba. By the mid-1960s Sebey was playing for the national team, winning gold at the 1966 Central American and Caribbean Games in San Juan, followed by bronze a year later at the Pan American Games in Winnipeg. The Cuban women’s volleyball team had more success in the early 1970s with a silver at the 1970 Central American and Caribbean Games, before winning gold at the 1971 Pan American Games. One year later Sebey was selected to compete at the München Olympics, but the Cuban team had a disappointing Games, finishing sixth out of the eight teams that took part. After her competitive career she worked as a coach for many years with different teams across the Caribbean.
