Born and raised in Neptune, New Jersey, Dennis has appeared in over 40 television shows and films since starting his acting career.
He started traveling to New York shortly after high school where he attended the Lee Strasberg Theater Institute. A couple years later he headed out west to Los Angeles and started studying at the legendary Stella Adler Academy of Acting in Hollywood. In one of the last groups with Stella Adler, Dennis was fortunate enough to audition and get cast alongside ten other actors to form a new version of the historic Group Theater, “Cafe 1651” named after the address of the school shortly before Stella’s passing.
He stars in the just-released feature film, Chasing Bullitt about the life of actor Steve McQueen where he appears as Agent Freddie Fields, and also in the Oscar-winning feature film, Green Book as Mags with Viggo Mortensen and Mahershala Ali.
