When the Dartmouth Aires burst onto the national stage... of NBC’s ... The Sing-Off, it was impossible to miss Clark Moore. With his signature hairstyle, his beautiful tenor voice, and his acrobatic dance moves Moore made an indelible impression.
Clark has an amazing voice, and he’s a wonderful dancer—two major skills which give you an advantage in getting cast on Glee. However, most importantly, Clark is unique. When casting Glee, I am particularly interested in finding people who are extremely talented, as well as one of a kind. Clark possesses all of these qualities.

Moore has successfully juggled his career and his performance as a student, according to Heck.

“He has used every moment that he can to further his training and to make the connections that he needs in order to become part of the entertainment business, but he has also been very attentive to his work here at Dartmouth and to his responsibilities as a student,” Heck said.
