Iván Calderón is a former professional boxer from Puerto Rico who lives out his passion for the sport by running a municipal boxing gym in Guaynabo.

Now 44 years old, Calderón won belts in two weight classes during a career that saw him go 35-3-1 and earn the title of “super champion” from the World Boxing Organization. These days, Calderón coaches and mentors athletes at the Amelia Municipal Boxing Gym, where he trains boxers ranging from those looking for exercise to those pursuing a career in the sport.
