You name it, literally, I've DONE it.
Movie trailers, ADR, commercials, industrials, book on tape, animation, car navigation systems, ringtones, ringbacks, toys, radio shows, video games, dubbing, theater announcing... and whatever they invent in the digital world tomorrow.
I've been spokesman in commercials for SBC Yahoo!, Earthlink, Compass Bank, Skaggs Alpha Beta markets, Schnucks markets, The MAC Card, White Castle burgers, TGI Friday's restaurants, The Black Eyed Pea restaurants, Food Lion, Kash n' Karry markets... more than I can remember.
In animation I've been on Rugrats, Boondocks, Angry Beavers, Pinky and The Brain, Scooby Doo and Shaggy Get a Clue, Johnny Bravo and many others. All the major studios. And of course, "This Land" from Jibjab.com. which was the viral sensation of the last election.
Go to my website and poke around. Hear my many voice samples.
I studied voiceovers with a guy in New York, the voice of Nabisco for a LONG time, Mr. Harlan Rector.
The rest I really got on the job. It didn't hurt that I grew up in a professional acting household; my mom is Golden Globe and Emmy nominee, actress Marion Ross.
