d'Auguste's first experience with martial arts came in April 1996; previously, she had taken ballet and modern dance. Her mother, Anita d'Auguste, signed her up for a Woman's Safe Seminar at Tiger Schulmann's Karate Center, where she learnt basic grab escapes and strikes. This came at a difficult time for the unemployed d'Auguste, who had recently left an abusive marriage, taking a 3 year old daughter along with her. Her escape to New York from Arizona had to be planned carefully; her husband had threatened to kill her if she ever left.
d'Auguste had already spent all her money on child care and nursing school, but knew she needed further self-defence training. Sensei Peter Guzman, an instructor at the school, made an agreement with d'Auguste that she could work off her tuition fees through various chores at the gym; for example, taking calls, mopping the floors and cleaning the locker room. Soon, she was training regularly, eventually earning her 2nd degree black belt and level 2 Joshu.
d'Auguste began competing in MMA in 2000 for the TSK Fight Team, later becoming the top ranked female fighter in the world. Her last fight was a win against Megumi Yabushita at Smack Girl: Dynamic on 17 August 2005.
