Spotlight: Marcus Sebastian Mason – The Madison Group


Marcus Sebastian Mason is Senior Partner at The Madison Group (TMG). He is responsible for managing the firm’s transportation, energy, tax, telecom and homeland security portfolio. In addition he focuses on crisis management, complex integrated campaigns and coalition building. Mason comes to the firm with more than fifteen years of political and policy experience from the National Railroad Passenger Corporation – Amtrak (NPRC).

According to the November 3, 1993 issue of Ebony Magazine, Marcus Sebastian Mason is the youngest person to have successfully managed a campaign for the United States Congress. At the age of 21, Mason managed the 1992 contest between Compton Mayor Walter R. Tucker, III and Compton School Board Member Lynn Dymally, daughter of then Congressman Mervyn Dymally, that resulted in a primary victory for then Mayor Tucker. Following the primary, Mason managed a general election campaign that yielded one of the highest margins of victory for a congressional candidate that year. Despite the near three-to-one funding advantage that Dymally enjoyed over Tucker, Mason’s ability to build coalitions among labor organizations, activists and the ecuminical community proved valuable. Mason also implemented a strategy that organized key areas of the newly formed congressional district at the precinct level in an effort to increase voter turnout among certain demographics.

As the principal staff member for the California Transportation Task Force in the United States House of Representatives, Marcus was responsible for leading Task Force’s efforts on fact finding missions and conducting field hearings throughout the State of California to assess the aviation, rail and ground transportation infrastructure needs of large, medium and small cities in preparation for the reauthorizations of the Transportation Equity Act (TEA-21) and Aviation Investment and Reform Act for the 21st Century (AIR-21).

In addition to his accomplishments in the Nation’s Capitol, Mr. Mason has successfully managed political campaigns at the Federal and local level, winning his first congressional campaign at the age of 21 before becoming a Chief of Staff to a Member of Congress at age 22.

Mr. Mason is also a member of the board of directors of the Congressional Black Caucus Foundation (CBCF) and previously served on the CBCF’s Corporate Advisory Council (CAC). He is also on the board of directors Congressional Black Caucus Political Action Committee (CBC-PAC) and also serves as President of the Board of Directors for the Washington Government Relations Group (WGRG), a non-partisan independent, volunteer association founded to enrich the careers and leadership abilities of African-American government relations professionals.
