Mark Mahoney Jr., 38, of Westmont, passed away unexpectedly March 14, 2021, at the home he loved to work on.
Mark was born in 1982 in Waukegan. Mark was vice president of front office solutions for Northern Trust. He was a financial wizard and had a great passion for his work. He was an avid Notre Dame fan with many superstitions and would never miss watching a game live. Mark was a fixer of all things broken and would lend a hand to anyone in need and give them the shirt off his back.
He was Fozzie’s favorite human. Mark was a generous and selfless man whose infectious smile could light up any room. Most importantly, he loved his wife, family and friends fiercely.
Mark is survived by his wife, Christine Cassa; his parents, Mark Sr. and Linda Mahoney, née Frum; his siblings, Michael (Victoria) and Susan Mahoney; his grandparents, Gene and Tina Frum; his in-law, Anthony and Susan Cassa; his sister-in-law, Stephanie (Tim) Arena; and his nephew and niece, Michael and Connor Arena.
