On May 7, 1955 Donald married the love of his life, Jean Petrowski. They loved trips up north to Tawas and down south to Florida. Donald was a lifelong member of St. Mary's Catholic Church. Most mornings you could find him with his friends having coffee at McDonalds. He enjoyed everything outdoors; from golfing, snowmobiling, boating, riding his motorcycle, watching deer, his John Deer Tractor, and tending to the yard. He had a need for speed and loved sports cars, especially his Corvette’s.

Donald made friends wherever he went. But above all, he cherished every moment spent with his family; especially his grandchildren. Donald was a wonderful man and will be deeply missed by all.
