     Mr. Costello, a Washington native, was a 1937 graduate of Gonzaga High School and a 1942 graduate of Columbus Law School, what is now Catholic University’s law school. It was in law school that he met his wife, a fellow student, Helen O’Brien. The couple were married for over 50 years and had six children.

     John was a founding member of St. Catherine’s Laboure Catholic Church in Wheaton and helped start its Catholic Youth Organization. He was also President of the Parent/Teacher Association, a member of the Holy Name Society and Chairman of the Fundraising Campaign for each of the churches there. Later, Mr. Costello was a long time member of St. Patrick’s Catholic Church in Rockville before joining Our Lady of Grace Catholic Church at Leisure World.
