O’Neill Monahan took over the role of Rocco Falconeri on General Hospital in 2017 when the role was recast. O’Neill filmed his first episode on the police station set as Rocco visited his father at work, and appeared in several episodes that year as Rocco navigated suddenly having a sister, and the family scenes that brought as his Mom tried to bond with her. In 2019, he was given a few episodes with heavier material as the show addressed how Rocco has been feeling with his Dad gone, and he last aired that same year.
O’Neill’s first time on a soap was an episode of Days of Our Lives in 2015 as Young Chase.
