John "Johnny" Hamilton
John Robert Hamilton, 82, of Jefferson peacefully passed away at home with his family around him on Nov. 9, 2025. Known by his family and friends as "Johnny," he was born on Aug. 6, 1943, to Robert John and Kathleen Karol (Wilt) Hamilton in Jefferson, Iowa. He grew up in Jefferson, graduating from Jefferson High School in 1961.
He met the love of his life and future business partner, Alice Grote, at the Starline Ballroom in Carroll, Iowa. They were married on July 13, 1963, at Our Lady of Mount Carmel Church in Mount Carmel, Iowa. Four sons were born to this union: Bob, Mark, Johnny, and Danny. After graduating from high school, Johnny worked in his father's trucking and fertilizer business. It wasn't long after that he started his own trucking and excavation company. In 1976, Johnny and Alice added a ready-mixed concrete business, Greene County Redi-Mix, later known as Hamilton Redi-Mix. His work ethic and perseverance endeared him to his many customers.
In his younger years he enjoyed stock car racing, snowmobiling and snow skiing with his family and friends. He also loved boats of all kinds and had many different boats during his lifetime. He particularly loved boating and entertaining his family and friends in the Florida Keys and at Lake Panorama. He was a member of St Joseph Catholic Church and the Knights of Columbus.
His family and friends were most important to him. He was a proud grandpa to five grandchildren and eight great grandchildren, spending as much time as he could with them and enjoying their many activities.
