I worked with Hunter and he is a terrific colleague (and he goes by Hunter -- like many actors, he simply uses his middle name professionally). Very few people graduate college on a Friday and sign a production contract the next week; he got very lucky that his first job out of school was a major role in a prestigious Broadway revival.
As Kad already mentioned, he works quite frequently. His career is following the trajectory of many young actors who primarily work in theater -- regional gigs, cabaret, workshops, concerts.
