The DeCenzo family has always been into art – Gianni’s parents even met in an acting class. This meant that when eight-year-old Gianni said he wanted to be an actor, his parents couldn’t refuse him. His mother immediately took some pictures of him in the backyard, sent them out, and soon secured a talent manager for Gianni.

Not much is known regarding Gianni’s educational background. He attended a local elementary school, until he became active in the entertainment industry, and couldn’t keep up with school, so he was then home-schooled.

Gianni got his big break when he landed the recurring role of Demetri in “Cobra Kai” (2018), an action drama series based on “The Karate Kid” by Robert Mark Kamen. His character represented a socially awkward high school teenager, who became more confident in his own strength after joining Miyagi-Do Karate. He starred in the martial arts series filmed in Atlanta, Georgia, alongside popular actors such as Mary Mouser, Jacob Bertrand and Martin Kove.

In 2020, he reprised his character Demetri, this time as a voice actor in Cobra Kai Video Game.
