About Supervisor Juan Miguel Martinez

Juan Miguel Martinez is a lifelong resident of Milwaukee, and a product of Milwaukee Public Schools. He majored in Creative Writing at Milwaukee High School of the Arts and worked on the school newspaper. Growing up on the north and south side of Milwaukee as the son of Mexican immigrants gave him a lens into the everyday working class struggles that the people fought and it fueled him to serve his community.

He worked as an English teacher in Mexico City, and upon returning to the United States, worked alongside his father at Grede Foundries, and later, the D.R. Diedrich tannery. Working physically demanding jobs is something he is no stranger to, and later went on to work in customer service for Kohl’s and ASQ. After working these kinds of jobs as long as he did, he decided to start documenting the issues workers had and moved into freelance journalism, and found writing jobs with Urban Milwaukee, Milwaukee Record, Shepherd Express, El Conquistador and Artdose Magazine, for which he still currently writes.

He became a union organizer for Milwaukee Area Service and hospitality workers in 2020 and applied all of this knowledge in his run for County Board Supervisor in 2022. He feels that everyone in the district deserves a voice and to be organized, which is why he plans to treat the district as a union, relaying the needs of the community to the County Board. Juan Miguel vows to restore power to the working class through being a representative of collective action.
