Short answers, pulled from the story.
Anna Kozlova is a former synchronized swimmer born on the 30th of December 1972 in Leningrad, Soviet Union. She competed in three Olympic Games, first representing the Unified Team at the 1992 Barcelona Olympics and later the United States at the 2000 Sydney and 2004 Athens Games.
Kozlova defected to the United States in 1993, a decision she traced to her impression of the American team at the 1989 World Cup in Paris. After the 1993 European Aquatics Championships in Sheffield, she flew to California for a teammate's wedding and did not return to Russia.
Kozlova did not compete at the 1996 Atlanta Olympics. She was waiting to receive U.S. citizenship, which she obtained on the 7th of October 1999, and was ineligible for international competition in the intervening years.
At the 2004 Summer Olympics in Athens, Kozlova won two bronze medals. She earned the first with partner Alison Bartosik in the duet competition and the second as a member of the U.S. team in the team event.
Kozlova won duet gold at the 1991 European Aquatics Championships in Athens, partnering with Olga Sedakova. She and Sedakova repeated as duet gold medalists at the 1993 European Aquatics Championships in Sheffield, which was also the last time the two competed together.
Kozlova trained with the Santa Clara Aquamaids in Santa Clara, California, under Hall of Fame head coach Gail Emery. During that period she won national titles in solo, duet, and team competitions multiple times before receiving her U.S. citizenship in 1999.
