Mike sold Haulmark in 2002 to an investment group and shifted his focus and free time to his family. He never missed a chance to spend time with his grandchildren, picking them up from school, playing golf with them, attending their tennis matches, soccer matches, football games, lacrosse matches, plays or just hanging out with them; he was busy shaping their lives..

Mike also served on the board for the Bristol Branch of Key Bank in Indiana and the Barefoot Beach board of directors in Bonita Springs.. Even through his battle with cancer, Mike continued to guide and lead Mark Line and be a mentor to his son, Matt, as he founded his own company. Mike's passion and leadership gave him strength and lifted his spirits in hard times.. Mike will be greatly missed by his wife, children, grandchildren, employees, suppliers, customers, daughter-in-law, son-in-law and the people he has touched along the way. Over the years, the most precious gift he has shared has been his time and his desire to make others feel special.
