Born in East Boston in 1946 and ordained for the Archdiocese of Boston in 1979, Father Tom has faithfully served in pastoral roles across Massachusetts, including 25 years as administrator of Holy Rosary Church in Winthrop and currently as a senior priest in residence at St. John the Baptist in Quincy. Since 1984, he has led the Catholic evangelistic ministry In Season & Out of Season, which now broadcasts across 10 stations nationwide and through cable outlets in New England.

As a pivotal figure in the Catholic Charismatic Renewal for over forty years, Father Tom is known for passionate preaching, spiritual authority, and a heart for revitalizing parish life through Scripture-based inspiration and renewal. His program consistently encourages listeners to live boldly for Christ, in both seasons of abundance and challenge, by faithfully proclaiming the Gospel and inviting deeper transformation. His battle cry and radio program slogan was: “In the presence of God and of Christ Jesus, who will judge the living and the dead, and in view of his appearing and his kingdom, I give you this charge: Preach the word; be prepared in season and out of season; correct, rebuke and encourage—with great patience and careful instruction.” — 2 Timothy 4:1–2
