Obituary for Thomas M. O’Donnell

Thomas M. O’Donnell of Warrington passed away on Sunday January 22, 2023 at Doylestown Hospital. He was 85 years old. Tom was the husband of the late Lois E. (Gilmore) O’Donnell.

Born in 1937, he was the son of the late John P. O’Donnell and Gertrude E. O'Donnell and was one of seven (7) children, John P. O’Donnell (Diane), the late James O’Donnell (Susan), Gertrude O’Donnell, Geraldine O’Donnell, Francis O’Donnell (Roseanne) and Eileen Krokenberger.

Tom had attended North Catholic High School. He went on to LaSalle College where he received his degree in accounting.

Tom spent most of his professional life as a systems analyst. He went on to start and own several businesses, including RMS Data Services.

Tom’s truest and deepest passion was his love of tennis where 7 days in a week wasn’t enough to fulfill his time on the court. Summer evenings Tom could be found sitting by his pool with the Phillies on in the background and loud noises could also be heard from Sorrel Road on NFL Sundays in the fall.

Tom is survived by his partner, Diane Terry. His three (3) sons; Thomas C. O’Donnell (Deb), Timothy R. O’Donnell (Kelly), and Sean P. O’Donnell (Julie). He is also survived by his ten (10) grandchildren Timothy, Ryan, Charity, Dylan, Kaelin, Brooke, Garrison, Riley, Julia and Sean and six (6) great grandchildren Hunter, Brenna, Ryan, Maddox, Ledger, and Keanu.
