Michelle Steel

Michelle Steel

Orange County Board of Supervisors,
Supervisor, Second District

Michelle Steel is Chairwoman of the Orange County Board of Supervisors and Supervisor for the Second District of Orange County. Since 2014, she has represented the residents of Costa Mesa, Cypress, Huntington Beach, La Palma, Los Alamitos, Newport Beach, Seal Beach, Stanton, the unincorporated area of Rossmoor, and portions of Buena Park and Fountain Valley.

A business leader and taxpayer advocate, Steel previously served as Vice Chair of the State Board of Equalization, representing more than 8 million people in Southern California. As a member of the board, Steel distinguished herself as the state’s leading tax fighter. Her first-term achievement was the discovery that the Board of Equalization had delayed the return of millions in security deposits owed to California businesses. Following her investigation, the agency refunded tax security deposits worth upward of $50,000 each to more than 5,500 small businesses. Procedures were changed and improved due to Steel’s leadership. In 2013, Steel succeeded in eliminating the agency’s automatic security deposit program, freeing thousands of new businesses to use their scarce capital to create jobs and grow the economy.

Over the past decade, Supervisor Steel has served on the President’s Advisory Commission on Asian Americans and Pacific Islanders, California World Trade Commission, Los Angeles County Department of Children and Family Services, and Los Angeles Airport and Fire Commissions.

Supervisor Steel holds a degree in Business from Pepperdine University and an Executive MBA from the University of Southern California. She is fluent in Korean and Japanese. Steel and her husband, Shawn, have been married since 1981.
