Tom was a retired employee of Alcosan, where he worked as a computer programmer.  Tom was a devout Christian and longtime member of Murrysville Alliance Church.  His greatest joy in life was spending time with his family, especially his grandchildren.  Tom treasured the memories shared at his grandkid’s baseball and softball games, teaching them to fish, and vacationing with them to Disney, Kalahari Resort, and many other destinations.    

Tom will forever be remembered as a man of few words, but a heart full of love.  He lived each day by his favorite saying, “It is what it is.”

All are welcome to attend a Memorial Service at the Murrysville Alliance Church on Saturday, July 11 at 10 a.m.

Arrangements are entrusted to Patrick T. Lanigan Funeral Home & Crematory, Inc., Turtle Creek / Monroeville Chapel, 1111 Monroeville Ave., Turtle Creek, 412-823-9350.
