[1] While she is better known as a boxer, she has also posed as a model for various magazines, often wearing sports bikinis and boxing gloves.
Demick's professional boxing career began on March 26, 1999, when she knocked out experienced Karen Rios in the first round, at Hialeah, Florida.
After winning her first three fights by knockout, Demick and her managing team felt it was time to step up in her opposition's quality level, so Demick fought Puerto Rican Daisy Ocasio and former world champion Marsha Valley, losing back to back six round unanimous decisions to them.
She challenged Karla Redo for the WIBA's world Welterweight title, in Ft. Lauderdale, Florida.
Demick made history for Chilean boxing that night, but her joy only lasted a few hours, because it was discovered that the judges had added their scorecards wrongly, therefore, Demick ultimately ended up losing the fight by an eight round decision.
