Not satisfied with being a teacher, Ferraro decided to go to law school. She taught in the second year of full-time teaching during the day and passed the bar exam in 1961. Zaccaro runs a successful real estate business and Ferraro began working as a civil lawyer for his company; after they got married, she retained her maiden name to Professional use. In addition to working for Zaccaro, Ferraro also did some public welfare work and began to engage with various members of the New York City Democratic Party. In 1974, she was appointed as an assistant district attorney in Queens and was assigned to work in the Special Victims Bureau, where she prosecuted cases of sexual assault, domestic violence and child abuse. Within a few years, she served as the head of the department and in 1978 she entered the US Supreme Court Bar Association. Ferraro found out that her work with the abused children and other victims was exhausted and decided that it was time to move on. A friend of the Democratic Party persuaded her that it was time to use her reputation as a strict prosecutor and run for the US House of Representatives.
