Woo moved once again with his parents to Round Rock, Texas, a suburb of Austin, where his father had been transferred by IBM. He continued performing in middle school and high school as well as at Austin’s Zachary Scott Theatre, where he took classes and acted in plays.

Soon after he graduated from high school, Woo decided to move to New York City to pursue a career in performing, only one week after 9/11. There, he studied at the American Academy of Dramatic Arts and the T. Schreiber Studio. Woo garnered numerous roles in off-off-Broadway theatre and for underground performance artists.

In 2004, Woo was enlisted as a VJ for MTV Chi when the network was launched for an Asian-American viewership. One year later, he segued to a two-year stint as VJ for that network’s follow-up program, MTV Iggy, during which time Woo—raised as an all-American boy—learned about his Chinese culture and heritage as well as the whole range of the Asian pop scene.
Woo appeared on an episode of Nickelodeon’s series “The Naked Brothers Band” in 2008, but his two lines of dialogue were given to skateboarding legend Tony Hawk, who was a guest on that episode. However, the following year, he was selected for the role of Sun Lok in “The Sorcerer’s Apprentice” over considerable competition.

Following the completion of his work on “The Sorcerer’s Apprentice,” Woo moved westward to Los Angeles to continue pursuing his professional acting career.
