Dennis was providing sports statistics in his high school days and his analysis of the numbers continues to this day. He played high school baseball but his high school football career was cut short by a knee injury. He has also earned a reputation in South Jersey as a basketball public address announcer who brings excitement to the game. Though he tries to be impartial with his analysis, Dennis has been known to paint his face orange and black for Flyers games. He recently began a new career as a high school teacher and, after seven years as an assistant coach, became head girls basketball coach at his alma mater.
