After moving to New York City to attend the New York University Tisch School of the Arts, he worked in theater on various productions around the country. He met Crispin Freeman while working on a production of *Romeo & Juliet* in Cincinnati, Ohio, which helped him get voice-over work back in New York.

He describes Cumore from *Tales of Vesperia* as "slightly unhinged". In *Darksiders*, he voices the lead character War, one of the Four Horsemen of the Apocalypse. He describes his voicing as deeper than his usual voice, and that he portrayed War as a fairly old soul who isn't surprised at the events around him. In the video game-based film *Final Fantasy VII: Advent Children*, he voiced Red XIII. In addition to voice acting, he has worked as a voice director and writer on various video games and anime shows.

After becoming hugely successful, the *Critical Role* cast left the Geek & Sundry network in early 2019 and set up their own production company, Critical Role Productions. Soon after, they aimed to raise $750,000 on Kickstarter to create an animated series of their first campaign, but ended up raising over $11 million.
