Dennis Michael Quinn, age 47, passed away on Tuesday, February 3, 2026. He was born in Chicago, Illinois, and carried his love for the city with him throughout his life.
Dennis is survived by his son, Matteo Quinn; his mother, Jolene Quinn; his brother, Corey Quinn; his sister, Colleen Quinn Schnepf; and his partner in life, Nikki Demicelli, with whom he shared a home and a life full of love. He is also fondly remembered by his loyal four-legged companions, Major and Meadow.
Dennis had a deep love for Chicago sports, cheering faithfully for the Bears and the Cubs through every season. Some of his happiest moments were spent fishing with his “good buddy” Jim and the “Bassholes,” where laughter and friendship were as important as the catch. He will be remembered for his big heart, his loyalty to those he loved, and the joy he found in simple moments shared with family and friends.
A memorial service will be held at the Ocotillo HOA Lakeside Gazebo, 3315 S. Price Rd, Chandler, AZ, on Saturday, February 7, 2026, at 10:00 a.m., followed by a Celebration of Life at Dennis and Nikki’s home.
In lieu of flowers, memorial donations may be made to the American Diabetes Association in Dennis’s honor.
