She competed for the United States in the 1992 Summer Olympics held in Barcelona, Spain in the 4 x 400 meters where she won the silver medal with her teammates Natasha Kaiser, Gwen Torrence and Rochelle Stevens.

She returned to the 1996 Summer Olympics in Atlanta, U.S. where she again ran with Rochelle Stevens and fellow Americans Maicel Malone and Kim Graham to win the gold medal in the 4 x 400 meters.

She made a third appearance in the Olympics in the 2000 Summer Olympics held in Sydney, Australia and again walked off with the gold medal in the 4 x 400 metres with her teammates Monique Hennagan, Marion Jones and LaTasha Colander-Richardson.

This medal was later stripped due to steroid doping admissions of Marion Jones.

However, she and 6 other members of the team would successfully appeal the decision to strip them of their medals in July 2010.
