MENDOTA – After 21 years of serving as the city of Mendota’s Police Chief, Thomas Smith announced his resignation effective Wednesday. At his last city council meeting, Chief Smith gave an emotional farewell to council members, praising Mayor Boelk for his leadership and friendship over the years. Having worked for two different police departments for 44 years, Smith says the city of Mendota has been the most rewarding part of his career. He says the Mendota Police Department is award winning because of its officers and support from the community, making Mendota the world’s greatest little city. Chief Greg Kellen took over the department in early December of last year.
