Titus, born in Honolulu, Hawaii, was destined for a life in show business from a young age. As the child of a military family, he was frequently relocated, which provided him with the unique opportunity to be exposed to various forms of entertainment. This exposure sparked his passion for performing, and by the age of nine, he was already dancing and singing in his elementary school talent show. He continued to hone his skills, taking voice lessons in middle school, but it wasn't until his senior year of high school that he began acting, securing a lead role in his first musical, "1940's Radio Hour".
After graduating from Buena High School in Sierra Vista, Arizona, Titus was accepted into The New York Conservatory for Dramatic Arts' professional training program. During his first year, he supplemented his education with a job as a New York Knicks Acroback Tumbler, performing during half times at Madison Square Garden. He also danced with the NY Liberty, a co-ed hip-hop dance team for the WNBA. However, upon graduating, Titus relocated to Los Angeles to pursue his entertainment career on a professional level.
Titus soon found success as a recurring character on Fox's hit show "Glee", and he returned for the show's second season. He played the role of David, a friend of Blaine's (Darren Criss) and a Warbler at the Dalton Academy. In addition to his work on "Glee", Titus has also starred in the NBC Walmart/P&G family movie night film "Game of Your Life", co-starring Lea Thompson and Nathan Kress, and has a leading role alongside Lucy Hale in the new ABC Family original movie "A Cinderella Story: Once Upon A Song", set to premiere in February 2012. Titus has also appeared in episodic work, including "The Closer" with Kyra Sedgwick, and has made various international appearances and tours related to "Glee".
