Mary Jo McCoy

Mary Jo McCoy (née Giambrone), M.D., of Waukesha, Wisconsin, passed away on January 28, 2026. Born on June 7, 1961, to Joseph and Dorothy Giambrone (née Mock) in Chicago, Illinois, she dedicated her life to healing others. She earned her medical degree from Northwestern University and built a distinguished career as a family physician at Advocate Aurora Health Center - Edgerton Clinic where she was known for her sharp intellect, unwavering empathy, and tireless commitment to her patients.

Beyond her professional life, Mary Jo had a quick wit and loved sharing clever stories and playful observations. She found joy in making those around her laugh - often at her own expense. To those who knew her heart, she was endlessly kind, generous, and fiercely loyal. Mary Jo saw the best in everyone and offered support without hesitation.

The eldest of four children, Mary Jo is survived by her devoted husband of 39 years, Paul W. McCoy; her sister, Debbie (Jonathan) Jedd; her brother, John (Cindy) Giambrone; and her brother, Joseph (Vicki) Giambrone. Mary Jo was preceded in death by her loving parents and her cherished daughter, Emma Kathleen McCoy.
