Thomas Joseph Cusack, of South Boston, entered into eternity on July 16, 2025. Born August 16, 1955 to Bernard Cusack and Dorothy (Breen) Cusack, Tom was the beloved brother of Sheelagh McKillop of OH, Bernard Cusack of WA, and the late Michael Cusack. Tom is survived by his sweet and loving wife Deanna (Guarnotta) Cusack and his loving children Rev. Anthony Cusack and Maria L. Cusack. Devoted Husband, Father, Son, Brother, Uncle, Co-worker and Friend, Tom was known for his strong faith, his keen sense of humor, his kind nature, his mischievous spirit and his sharp suits. He will be deeply missed by his loving family who remains proud of the life he lived. So to borrow a phrase from his favorite film: That’s nice work, T.J.
Eternal rest grant unto him, Oh Lord, and may perpetual light shine upon him.
