Steadily working since the age of 2, transitioning from print advertorials and television commercials to voicing Mikey in the final installment of Kirstie Alley and John Travolta's Look Who's Talking trilogy, the New York City native has collected some 50 credits across his 30-plus year career.
Since graduating from his part as middle child Simon and then, subsequently, the University of Southern California, where he majored in film and television studies, the five-time Young Artist Award nominee and Teen Choice Award winner has appeared on Numb3rs, The Vampire Diaries and pretty much every version of CSI. In addition to voicing Riku in the Kingdom Hearts video game series, he's worked on crime series D.P.D. Echo 1.
