I think at some point, I decided that if I was really going to be a professional actor that it would take at least everything that I would have emotionally or physically and I knew that I really wanted to pursue art.
After performing as a show artist for The Hunchback of Notre Dame Musical Discovery Adventure North American Mall Tour in 1996, he transferred to Walt Disney Feature Animation in Burbank, California (now known as Walt Disney Animation Studios) in 1997 to work on his first feature, Tarzan as a storyboard artist.
While at Disney, from the late 1990s and throughout the 2000s, he did storyboards for The Emperor's New Groove, The Little Matchstick Girl, Home on the Range, Chicken Little, Meet the Robinsons, Tangled, and Gnomeo and Juliet, as well as storyboarding and developing the unproduced films Wild Life, My Peoples, and Rapunzel Unbraided (an early version of Tangled), Joe Jump, and King of the Elves.
Also, while at Disney, he provided the voices for Barry & Bob the Longhorns in Home on the Range (2004), Goosey Loosey for the animated film Chicken Little and its video game (2005), and for Rhino the hamster in Bolt (2008) for which he was nominated for an Annie Award for Voice Acting in a Feature Production, and the short film spin-off Super Rhino.
