Clark arrived fresh from West Virginia State College working as a "Girl Friday" for Color Magazine. She then earned her Masters of Library Science degree from Drexel University and a law degree from Temple University School of Law.
Clark served as councilwoman at large and majority whip on the City Council of Philadelphia, Pennsylvania. Clark was the second black woman in the history of Philadelphia to have served on the city council. In over twenty years of service, Clark compiled a distinctive record of accomplishments. As majority whip, she managed legislation and served as an integral part of the Council leadership team. Clark focused her energy on improving the city’s public schools and revitalizing the poor and under developed communities in Philadelphia.
