Colleen Eloise Giannangeli

Born and raised in Port Huron, Colleen was free-spirited and young at heart throughout her life. She built a long and distinguished career at Michigan Bell, eventually retiring as an accomplished executive. Work brought her to the metro-Detroit area, where colleagues came to regard her as a dedicated and thoughtful decision maker.

In 1991, Colleen married the love of her life, Peter Giannangeli. The two were inseparable, sharing a bond that was rare and beautiful. Colleen’s capacity to love was immense, and Pete received that love every day. Together they traveled widely—beginning with a honeymoon in Oahu, Hawaii, and continuing with cruises through the Caribbean and Bahamas. In retirement they took to the highways in their large RV, making friends and creating memories at military bases, parks, and attractions across the country. Winters often found them in Florida and Texas, where their RV became a second home.

Even when she was miles away, Colleen never failed to stay connected. She called, sent cards, and shared her amazing baked goods reminding family and friends they were in her thoughts. Colleen and Pete would not miss a family event if they were able. Her devotion to those she loved was constant and deeply felt.

Colleen was preceded in death by her beloved husband, Peter Giannangeli. She is survived by her sister; Sandra Gahns, Brother; Darwin Laming and a large and devoted family who will cherish her memory.

A funeral service will be held on Monday, October 26, 2026, at Hill Funeral Home, 11723 S. Saginaw, Grand Blanc, MI 48439. Visitation begins at 11:00 a.m., with the service at 12:00 p.m. a luncheon will follow. Colleen will be laid to rest at Great Lakes Cemetery.

In lieu of flowers, memorial contributions may be made to St. Jude Children’s Research Hospital and Heart to Heart Hospice.
