During his one year on staff, FAU made it to the championship game of the Gainesville Regional where they were defeated by the Florida Gators.

Fiorentino joined the Chipola College coaching staff in the summer of 2015, working primarily with the infielders, catchers, hitters and base runners. Fiorentino helped guide the Indians to back-to-back Junior College World Series championship titles in 2017 and 2018.

There have been 20 players selected in the Major League Baseball Amateur Draft during his first four years on staff at Chipola.
