About Mia St. John
She is known as the Knockout, and for good reason. Since blasting into women's boxing in 1997, Mia St. John has earned a reputation as a formidable fighter, with one distinction: She looks more like a movie star than like an undefeated (12 wins, including seven knockouts) featherweight.
