John was born in Philadelphia, Pennsylvania on December, 28, 1932, to his father John Leonowicz and mother Victoria Banarzok. He was one of five children.

He enlisted in the Navy in June of 1951 and worked as a Physician’s Assistant on the Aircraft Carrier USS Lake Champlain (CVA39) as well as various Navy assignments in local hospitals, including one in New London, CT where he met his future wife, Mary Orfitelli of Manchester, CT who was a nurse there. While serving in the Navy he received various medals of honor including the United Nations Service Medal, The European Occupational Medal, the Korean Presidential Unit Citation, and the National Defense Service Medal.
