In 2006, Michelle was elected to the California Board of Equalization. Throughout her tenure she was the country’s highest ranking Korean-American officeholder and California’s highest ranking Republican woman.
As a member of the Board of Equalization she promised to oppose all new taxes and tax increases, and when adjudicating tax appeals, presume a taxpayer is innocent until proved guilty. She also led the fight to return over $400 million to California taxpayers who were victims of a failed tax system.
In 2014, she defeated incumbent Allen Mansoor to win the District 2 seat on the Orange County Board of Supervisors. She served as Vice Chairman in 2016 and was unanimously elected to serve as Chair for 2017. In 2018, she was re-elected with 63% of the vote, easily avoiding the need for a runoff.
Michelle immigrated to the United States as a young adult with her mother and two sisters.
