Antonio is also recognized as a leader who reaches across the aisle to get things done.

During her tenure in the Ohio legislature, Antonio has introduced the Ohio Fairness Act, which would provide civil rights protections for members of the LGBTQ community. She continues to work to remedy and end Ohio’s use of the death penalty, as well as on an array of other bills focused on improving the lives of all Ohioans. Antonio continues to be an established expert in health policy in the General Assembly.


The first in her family to graduate from college, she holds both an MPA and a B.S. Ed. from Cleveland State University, and she was named a CSU Distinguished Alumni in 2013. She is also an alumnus and Bohnett Fellow of the Kennedy School Harvard Leadership Program (2011) and has been the recipient of numerous awards as legislator of the year from various organizations during her tenure.


Her daughters, Ariel and Stacey, have made Antonio and her wife, Jean Kosmac, very proud as the girls engage in their adult life journeys.


Antonio has made a number of historical firsts in the Ohio General Assembly. In 2010, she became the first member of the LGBTQ community ever elected to the Ohio House of Representatives in the 208-year history of the Ohio General Assembly. She was also the first LGBTQ member to hold a leadership position, when she was elected Minority Whip in the 131st General Assembly. In 2018, she became the first woman ever to hold the Senate District 23 seat and the first member of the LGBTQ community ever elected to the Ohio Senate. She continues historic firsts with her Senate leadership position, of Minority Whip, then Assistant Minority Leader in 2021.
