Gutiérrez was born in Mexico, and immigrated to Chicago when she was 15 years old.[3] She worked as a counselor and community liaison for public schools, including Benito Juarez High School in Pilsen and Hernandez Middle School in Gage Park. Her interest in politics began as a volunteer in Chuy García's campaign for mayor in 2015.[4] She later worked as a district director for Cook County Commissioner Alma Anaya.[4][5]
In September 2022, Gutiérrez announced her campaign for alderperson of the 14th ward, along with an endorsement from U.S. Representative Chuy García.[6][7] The 14th ward seat had been held since 1969 by Ed Burke, who had been indicted in 2019 and was awaiting trial for corruption and racketeering charges.[8][9] Redistricting following the 2020 Census changed the boundaries of the 14th ward such that its Latino majority grew and some majority-white precincts that had heavily favored Burke were removed.[7][4] In November, Burke announced that he would not seek re-election.[10][11] After Burke's exit, Gutiérrez faced Raúl Reyes, a staff assistant in the City Clerk's office who had ties to Burke.[3][4][12][13] Gutiérrez received endorsements and contributions from state senator Celina Villaneuva, state representative Aaron Ortiz, and the SEIU Illinois Council PAC. In the February 2023 election, Gutiérrez won with over 65% of the vote.[14][2][3]
