Sparky cherished the time he spent with his friends and family, creating memories filled with joy, laughter, and love that will live on in the hearts of those he leaves behind. He enjoyed watching sports, playing poker, and shooting pool, and as a devoted fan of the Chicago Bears and White Sox, he cheered his teams with unwavering passion and loyalty. Above all, he will be remembered for the love he shared and the light he brought into the lives of those around him.
