In 2000, John Hieftje began his tenure as mayor of Ann Arbor, and every two years after that, Hiefjte won reelection with numbers reflecting strong support from the people in the city. His 14-year run makes him the city’s longest-serving leader.

He recently announced he is not planning on running for reelection, a decision he says he’s been considering for the past few years.
