Dean’s love of politics began around the family dinner table with her parents quizzing her and her six siblings on current events. After graduating from high school, Dean became a local committee member at age 18. She was the executive director of the Philadelphia Trial Lawyers and later opened her own three-woman law practice. Dean volunteered in politics before becoming a public servant herself. In the state legislature she championed progressive causes, and after the Sandy Hook Elementary School shooting she created the PA SAFE Caucus as a way of addressing the gun violence epidemic.
