Kelly, the headmaster at Seton Hall Prep since 1980, is well known and respected in a wide variety of circles in New Jersey. He is a longtime member of the Executive Committee of the NJSIAA and served as President of the organization in the early 1990s. With a life built on service, Msgr. Kelly has been active in various community affairs, including his involvement as chaplain to the Essex County Police and West Orange Rotary Club.
