Dennis C. Kilian, 78 of Lisle, IL, formerly of Westmont, IL, at rest September 14, 2025.  Born September 19, 1946, in Chicago, IL to Chester and Irene Kilian.

Only five months after the passing of his cherished wife, Janice, Dennis has now been reunited with her in heaven. Their love story was one of devotion and long-lasting love, and knowing they are together again brings peace and comfort to all who loved them.

Dennis was a proud and  loving father of Sharon Kilian, Denise Adkins-Siwierka (Kevin ) and Christina Fiandaca (Leo);

Proud Grandpa/Papa of Kayla Kucin, Dayna Ulrich, Quintin and Lillian Adkins, Ethan and Claire Siwierka, Madelyn and Charlize Fiandaca; Dearest brother of Diane Lapi (Alan). His legacy will continue on through the values he instilled, the love he gave, and the memories we will hold close.

Dennis was a quiet man by nature, with a thoughtful, caring spirit that touched everyone who knew him. His quick wit and gentle humor brought laughter to those fortunate enough to share in his company.

He found his greatest joy in the simple moments of life—being with his grandchildren and playing rummy or memory, sharing his love of fishing with his grandchildren, and cheering them on at their sporting events. He was immensely proud of all their accomplishments. He also enjoyed the fun of visiting the local casino and trying his luck at the slot machines.

Above all, Dennis will be remembered for the love he gave so freely to his family and the countless memories he created, which will continue to bring them comfort and joy.

In memory of Dennis, expressions of sympathy can be made through donations to the American Cancer Association. https://www.cancer.org
