Shifting from corporate America to the New York Fire Department proved to be a major culture shock for Regina Wilson. Upon joining the force in 1999, she became the 12th African-American woman in the FDNY's history and now is the first female president of the Vulcan Society, the African-American fraternal organization founded in 1940 to combat racial discrimination among firefighters. In the final ChangeMAKERS installment, Cristen and Caroline learn about Wilson's battle against sexism and hostility -- one she wages in order to do the job she loves and bring other women and people of color along behind her.
