John Supinski

On November 11, 2025, John Supinski went to join his beloved parents and sister in the home of our Lord. John was born in Chicago, where he met the love of his life and built a loving family. He spent 30 years working for the Cook County Highway Department and enjoyed vacationing in Wisconsin’s Northwoods.

Upon retirement, John moved to their small lakeside home to enjoy that beauty year round. He was a lover of God and country, college football, trains and fireworks, the louder the better.

John is survived by Kathryn (nee Nowinski) his wife of 61 years, four children; Diane, Jeffrey (Sandy), Keith (Katie), and Denise as well as seven grandchildren Kellie, David, Addison, Joshua, Laura, Emily and Victoria and one great-granddaughter Gracie. John showered love and gifts on them, especially at Christmas time.

Visitation for John will be held on Saturday, Nov. 15 from 9 to 11 a.m. at Holy Family Catholic Church with a funeral Mass at 11 a.m. and burial will follow at St. Patricks Cemetery in Woodruff.
