“Dr. den Boer is an avid golfer and member of Riverbend. He is a proud 5th generation member of the Trasse/den Boer family, who immigrated to Sheboygan from the Netherlands in the early 1900’s.  Three generations of his family worked at the Golf company, mainly in the foundry area. The majority of his father’s side of the family still resides in the Sheboygan area. He is excited to be the first person to play all 4 courses in 1 day (walking) and to raise money for local Sheboygan charities!
