Castronuova began her boxing career as a youth boxing trainer. Soon, she started entering local bouts, winning her first fight in 2002 at the NY Empire State Games in Syracuse. She also was a volunteer for a government-funded program designed to teach troubled youth the virtues of boxing and keep them off the streets. Later, while working as a personal fitness and boxing trainer at popular sports clubs in the New York City area, like Chelsea Piers and Gleason's Boxing Gym, she used fighting and boxing to encourage clients to “find their warrior within.” While continuing to train clients, Castronuova kept boxing competitively, winning a pair of “Silver Gloves” in 2004, the second-place prize in the Golden Gloves competition. Determined to redeem herself, Castronuova came back one year later and won her first New York Golden Gloves championship at Madison Square Garden in 2005 in front of a televised, capacity crowd. Following her first Golden Gloves win, she started competing nationally and was ranked #2 in the nation by USA Boxing. She went on to place in National boxing tournaments and win numerous titles, such as the NYABC title, the Metros, and the Empire State Games, and won her second Golden Gloves title in 2006 at Madison Square Garden. Certified as a boxing coach by the New York State Athletic Commission, she is also a personal trainer certified by ISSA.
