Brienne Brown

Brienne D. Brown (née Diebolt; born February 4, 1973) is an American educator and Democratic politician from Whitewater, Wisconsin. She is a member of the Wisconsin State Assembly, representing Wisconsin's 43rd Assembly district since 2025. She previously served on the Whitewater city council.

Early life and career Brienne Diebolt was born on February 4, 1973 in Landstuhl Germany, on an American airbase, to Mark Diebolt and Jean Diebolt (née Youngstrom). As a young child, Diebolt and her family moved to Iran, where her father served in a military attaché with the Shah of Iran, Mohammad Reza Shah. Eventually she and her family moved to Austin, Texas, where Diebolt attended Stephen F. Austin High School, graduating in 1991.

In 2012, Brown and her husband moved to Whitewater, Wisconsin, after Karl was offered a teaching position at the University of Wisconsin–Whitewater. Brienne began teaching community yoga and took on a role as an adjunct instructor at UW–Whitewater. She then ran again in 2019 in a different district, campaigning in support of building a grocery store, expanding the public library, and expanding public transportation services in Whitewater. In the 2019 election, she defeated incumbent alderman Chris Grady. She ultimately served three terms on the council.

In 2022, Brown ran for Wisconsin's 31st Assembly district against Republican Ellen Schutt, a former aid to then incumbent representative Amy Loudenbeck. During the campaign Brown was endorsed by Planned Parenthood. In the election, Schutt defeated her with a 18.38% margin, with Brown citing the legislative gerrymander as a factor in her defeat.

Following the 2024 redistricting, which undid Wisconsin's gerrymander, incumbent Democrat Jenna Jacobson was drawn out of her district and into the neighboring 50th district. Brown then declared her candidacy for the open 43rd district. Without a primary opponent, Brown advanced to the general election where she faced Republican legislator Scott Johnson, who had been drawn out of the 33rd district and into this one due to redistricting. A moderate Republican, Johnson had criticized his party over their refusal to accept the results of the 2020 United States Presidential election. The district had a projected margin of 16 points Democratic. In the election, Brown defeated Johnson with a narrow 51.24% of the vote. Brown took office on January 6, 2025.

In February 2025, Brown, alongside senator Kelda Roys proposed legislation to prevent landlords from engaging in price collusion. In August, the two legislators introduced legislation to prohibit concealed carry on college campuses in the state. In September, Brown, alongside senator LaTonya Johnson introduced legislation to amend the state constitution to include an equal rights amendment.

Personal life Brown lives with her husband, Karl, her two children, and their two pets in Whitewater.
