Since making his “General Hospital” debut, Giovanni Mazza has quickly become one of Port Charles’ breakout stars. While fans know him as the talented violinist Gio Palmieri, many may not realize the actor shares his character’s love of music in real life. Read on for five fast facts about the rising daytime star.
1. Giovanni Mazza Made His ‘General Hospital’ Debut in 2024
At just 19 years old, Giovanni Mazza made his daytime television debut on “General Hospital” in May 2024 as Gio Palmieri. The aspiring musician was introduced as a young man from Bensonhurst, Brooklyn, who had been raised by one of Lois Cerullo’s cousins in the same neighborhood where Lois and Sonny Corinthos grew up.
About a year after arriving in Port Charles to reconnect with family following the death of his mother, Gio’s life changed forever. He learned that the woman who raised him was actually his adoptive mother and that his biological parents were Brook Lynn Quartermaine and Dante Falconeri, making him a member of both the Corinthos and Quartermaine families.
2. Giovanni Mazza Began Playing the Violin at 3 Years Old
Mazza’s passion for music started early. He began playing the violin at just 3 years old before expanding his talents into acting at age 7.

Music has remained a defining part of Gio’s story.
