VIDEO: At 75-years young, Arnie Kleven has spent 50 of those years serving as a volunteer firefighter. “Back then you don’t think of it, but then you think where has the time gone?” Kleven said. It was 1972 when Kleven first joined up with Sun Prairie. He has spent the past four years in Illinois as a volunteer firefighter there. His house in Sun Prairie was near the old fire siren. “Every time the siren went off I would poke my head out,” Kleven remembers. “Finally one of the firemen said ‘Do you want to join the department?’ and I said ‘Sure.’” Chief Kleven served as Fire Chief from 1988 to 1993. He then stepped down to become a black hat firefighter but was quickly elected Assistant Chief. His last day will be on January 14th and he says he’s not sure what to expect.
