She put together a staggering amateur record, winning 105 of her 109 bouts. Competing primarily in the 54 kg (Bantamweight) division, she established herself as an elite international amateur through the Pan-American Women’s Championships:

Dionicius made her professional debut on her 23rd birthday, March 19, 2011. Operating initially around the 115–116 lb limit, she secured the South American Super Flyweight title within her first year.
On November 24, 2012, “La Gurisa” captured the vacant IBF World Female Super Flyweight Championship by defeating Michelle Preston via a dominant unanimous decision in front of her home crowd in Villaguay.
What followed was one of the most stable and impressive title reigns in modern women’s boxing. Dionicius successfully defended her IBF world title 12 consecutive times over a six-year span. She defeated top-tier global contenders, including Italy’s Simona Galassi and Mexico’s Guadalupe Martinez Guzman.
