Raised in the Western Addition neighborhood of San Francisco, Breed graduated with honors from Galileo High School before earning a B.A. from the University of California, Davis. After earning her B.A., Breed worked as an intern in the Office of Housing and Neighborhood Services for Mayor Willie Brown. In 2002, she became the executive director of the African American Art & Culture Complex, where she raised over $2.5 million to renovate the complex's 34,000 square foot space, including an art gallery, theater space, and a recording studio. Breed was named to the San Francisco Redevelopment Agency Commission in 2004. In 2010, Mayor Gavin Newsom appointed her to the San Francisco Fire Commission. In 2012, she earned an M.P.A. from the University of San Francisco.

Breed was elected to the Board of Supervisors in 2012 and elected its president in 2015. As president of the Board, Breed, according to the city charter, became the acting mayor of San Francisco following the death of Mayor Ed Lee. She served in this role from December 12, 2017, to January 23, 2018. After being rejected by the Board of Supervisors to serve as interim mayor in January 2018, Breed won the San Francisco mayoral special election held on June 5, 2018. Breed is the first African-American woman, second African-American after Willie Brown, and second woman after Dianne Feinstein to be elected mayor of San Francisco. She was sworn in as mayor on July 11, 2018.

Mayor Breed is working to create a more equitable and just San Francisco for all. Since February 2020, she has led San Francisco’s response to COVID-19, with a focus on slowing the spread of the virus and protecting the health of the most vulnerable. Her early and decisive actions to issue a Stay Home Order in mid-March have been credited with controlling the spread of COVID-19 in San Francisco, preventing the health care system from becoming overwhelmed, and saving lives. Under her leadership, the City has developed a network of COVID-19 vaccination sites with the capacity to vaccinate at least 20,000 people per day and is working to deliver vaccines as quickly and equitable as possible.
