Theresa "Terry" J. Oliver (née Santillo), beloved wife of the late Eugene "Gino" Oliver, passed away peacefully on May 17, 2026, and heaven gained an Angel that already has her wings. She leaves behind a legacy of love, wisdom, and warmth that touched everyone who knew her.

Terry was a devoted stepmom to Joseph "Jackie" Oliver and a proud grandmother to Joseph Dominic Oliver. She was the dearest sister of Guy (Paulette) Santillo and Judy Alesia, and the adored aunt of her late nephew, Guy (Gia) Santillo, and her nieces Denae (Nick Kuhn) Santillo, Donna Santillo, Tina (Tom Santangelo) Fioccola, Elissa Radley, and Stephanie Kafka. She was a great-aunt to many nieces and nephews and cherished by her dear friends.

A dedicated, longtime employee of the Cook County Clerk’s Office and Sportsman’s Park Race Track, She brought characteristic energy, kindness, and sharp wit to everything she did. Those fortunate enough to spend time with her always walked away richer, having learned from her wisdom and felt the embrace of her unconditional love.

While some leave only a footprint, Terry left an enduring memory and pieces of her beautiful hippie soul in the hearts of all who loved her.
