He was born on September 3, 1921. Fr. McMahon was ordained to the priesthood in Ireland on June 13, 1948 for the Diocese of Tucson. Upon his arrival he was served at St Cyril’s parish in Tucson, St Phillip Parish in Payson and then as pastor of St. Mary’s Parish with responsibilities at Seton High School. From 1959 through 1968 Fr. McMahon initiated the necessary elements to build a new facility for the elementary school, build a new convent, and add a new gymnasium at Seton.
