In Memoriam – Longtime AOS Member Chuck Esposito

Chuck Esposito passed away on January 23, 2017.  Here is a note from John Jakobsze on our long time friend and mentor:

“Some of you may be too young to remember Chuck Esposito! While Chuck was not a very large man, he was huge in stature and impact on AOS! He officiated in six (6) Football State Final Games across three (3) decades beginning in 1975. He was awarded NFHS Official of the Year for Football in 1984. He was a recipient of the John E. Katzler Life Time Achievement Award for his activity in AOS and helping new officials. He could always be counted on to stay late after meetings to discuss rule interpretations. Chuck also officiated basketball and baseball. He will be missed!”

Here is the obituary published in Chicago Suburban Daily Herald on Feb. 5, 2017:

SCHAUMBURG – Charles P. Esposito, 94, a resident of Schaumburg, formerly of Des Plaines and East Troy, WI, World War II Navy veteran, went to be with the Lord on January 23, 2017.
