Roberto Jimenez-Rivera got the most votes of anyone on the Chelsea ballot in November 2025. In January his colleagues elected him council president. He is, by both measures, the most broadly supported elected official in the city, and he did not grow up here.
Where he comes from
He was born in Norwood, the son of a teacher and a small business owner. His campaign biography says his parents moved the family back to Puerto Rico so he could grow up around relatives, and he finished high school there. He has a sister, Laura.
He went to the University of Michigan for both degrees, a bachelor’s in business administration in 2012 and a master’s in higher education the following year.
The job before the job
His career started in college admissions, working to widen access for low-income students and students of color. That work supplies the line he still repeats about the applicants he read for: “If I could do it, so could they. Why weren’t we giving them the chance?”
He came back to Massachusetts in 2014. He became a community organizer, worked on Ayanna Pressley’s first congressional campaign, and has organized with the Boston Teachers Union.
In 2019 he ran for the Chelsea School Committee and won as the highest vote-getter in that election. That is a pattern worth noticing: he has now topped the ballot in two different races for two different bodies.
What he works on
His stated priorities are education justice, housing, transit, environmental justice, state education funding, worker protections, and infrastructure.
Housing and zoning is where his name actually appears in the record. The council’s June 22, 2026 agenda lists two zoning amendments introduced by Council President Jimenez-Rivera: one to the Fitzpatrick-Prattville Smart Growth Overlay District, and one to the city’s Inclusionary Housing section. Those are the ordinances that determine what gets built in Chelsea and how much of it has to be affordable.
The family footnote
He is married to Sarah Neville, who serves on the Chelsea School Committee and was inaugurated for a new term at the same January ceremony. Their son Robi was born in 2020. At the inauguration he said of her that “I am a better leader for Chelsea because of her, and her leadership, both on and off the school committee, makes Chelsea a better place.”
Two members of one household holding two seats in city government is a fact worth stating plainly rather than leaving for someone to discover. The council and the school committee are separate bodies with separate powers.
The numbers
In the November 4, 2025 election he led the at-large field with 1,146 votes, ahead of Kelly Garcia at 1,081 and Leo Robinson at 1,040. Yessenia Alfaro took 631 and Nicholas Gregoretti 593. His term runs through 2027.
Sourcing: this profile draws on the Chelsea Record’s reporting, the councillor’s own published biography and professional profile where one exists, and the City Council’s posted meeting agendas. The city’s official council page lists each member’s seat and contact details but publishes no biographies and no committee assignments, so those could not be verified there.
