Mike spent most of his working days at Lakewood Sporting Goods, Custom Glass Products (CGP) and most recently at County Market. Special to Mike were the many adventurous outings with his dad and brothers navigating the northern lakes and catching the biggest fish, all while poking fun at one another and driving each other nuts. He also spent endless hours talking sports with his boys about the Packers, Brewers and any other sports or teams that interested Ben and Joe. He was always interested in what they got excited about and worked his hardest to learn and follow. Mike was also very proud of his grandkids and couldn't get enough stories and pictures.
