John Holyk, born in Muehldorf, Germany to Ukrainian parents Nicholas & Anna (Proroczyk), beloved husband to Kathleen (Zydowsky) Holyk, cherished father to Kaitlin (Nicholas) Holyk-Knoth, devoted brother to Rose (late Stanley) Wiszezur and Mary (Don) Ferrick. Fond brother-in-law to Lawrence (Kathryn) Zydowsky. Dear Uncle to many nieces and nephews including Lauren (Jacob) Pridgeon & Kristen (Josh) George. Devoted lifelong friend to George & Zenon Duda, Steve Wankewycz, & Oleh Hanowsky.

John's degrees in math, computer science and psychology paved his path in computer programming at DeSoto, Pactiv, & Kraft Foods. Words cannot describe what a great man he was. He knew how to make even the darkest moments light up with a few jokes. John will be sorely missed by his family and friends.
