Los Angeles City Councilmember, Tenth District  

Portrait of Mark Ridley Thomas

Mark Ridley-Thomas has distinguished himself as an effective leader and advocate for structural change for residents of Los Angeles for nearly four decades. In November 2020, he was elected to the Los Angeles City Council representing the Tenth District. He currently chairs the City Council’s Homelessness and Poverty Committee

After serving for 10 years as Executive Director of the Southern Christian Leadership Conference of Greater Los Angeles, Ridley-Thomas was elected to public office in 1991. He served on the Los Angeles City Council for nearly a dozen years representing the Eighth District, departing as Council President pro Tempore. He then was elected and served two terms in the California State Assembly, where he chaired the Jobs, Economic Development, and Economy Committee and the Assembly Democratic Caucus.

Ridley-Thomas went on to represent the 26th District in the California State Senate, where he chaired the Senate’s Committee on Business, Professions and Economic Development. While in the Senate, he served as the chair of the California Legislative Black Caucus in 2008 and led the Caucus in unprecedented levels of cooperation and collaboration with counterparts in the Latino and Asian-Pacific Islander Legislative Caucuses.

In 2008, he was elected to the Los Angeles County Board of Supervisors representing the Second District, where he served for a total of three terms, after being reelected in 2012 and 2016. At the Board of Supervisors, Ridley-Thomas authored and led LA County’s unprecedented effort to end homelessness through Measure H. He also championed the opening of the Martin Luther King Jr. Community Hospital after the King-Drew Medical Center shut down in 2007. The hospital now stands as the centerpiece of a transformed and state-of-the-art medical campus, within a community that has experienced over a billion dollars in investment in medical facilities, affordable housing, infrastructure and community-based improvements. 

Additionally, he served as on the Board of Directors of the Los Angeles County Metropolitan Transportation Authority, leading the effort to connect the region’s public transit system to the Los Angeles International Airport, and overseeing the construction of the Crenshaw/LAX Line. He also served on the boards of the Los Angeles Memorial Coliseum Commission and LA Care, the nation’s largest publicly operated health plan.

He is widely regarded as one of the foremost advocates of neighborhood participation in government decision-making by virtue of his founding of the Empowerment Congress, a 30-year initiative to foster neighborhood-based civic engagement. 

The Councilmember graduated from Manual Arts High School (Class of 1972) and then earned bachelor’s and master’s degrees, along with secondary and adult education credentials, from Immaculate Heart College. He went on to receive his Ph.D. in Social Ethics from the University of Southern California focusing on social criticism and social change.
