Andrea Stewart-Cousins was born and raised in New York to parents that encouraged a life grounded in education and service. From the very beginning of her public service in government - as the first African American to serve as the Director of Community Affairs in the City of Yonkers, Andrea Stewart-Cousins has espoused the values of empathy, empowerment and service. These values, coupled with her strong belief in advocating for the underserved and championing the needs of working families has distinguished her as a trailblazer in local and State government.

Prior to her election to the New York State Senate in 2006 to represent Greenburgh, Mount Pleasant and Yonkers, Andrea Stewart-Cousins served for a decade as a Westchester County Legislator. During her tenure (from 1996-2006), she was elected Majority Whip and Vice-Chair, and she authored and passed landmark legislation, including: Westchester County’s first human rights laws; living wage laws; smoke-free workplace laws; tougher gun laws; laws that prosecute "predatory lenders"; and laws that have provided tax cuts for seniors and veterans. As Chair of the Health Committee, Andrea Stewart-Cousins brought the "Sexual Assault Nurse Examiner Program" to Westchester County – after a successful pilot of this program in Yonkers. This model has since become a national cornerstone of enhanced community/medical rape crisis assistance.

Beginning in 1992 as the Director of Community Affairs for the City of Yonkers, Andrea Stewart-Cousins created an internship program for the hearing impaired and for children in working families. She has advocated for and contributed to the revitalization of the City of Yonkers and was a founder of the original "Art on Main Street," as well as a co-creator of "River Fest", which – in its seventeenth year – is a widely attended multi-cultural, ecologically oriented city-wide celebration.

Senator Stewart-Cousins is an advocate for human rights, quality education, accessible and affordable health care, youth development, environmental protections, and, making government more open, transparent and accountable to all of our citizens. Her belief that creating change locally affects changes on the State level has driven her legislative and policy agenda at home and in Albany. In her first term in the State Senate, she successfully fought to save the Community Hospital at Dobbs Ferry from closure, and worked with her colleagues in the State Legislature to provide additional funds for Yonkers city services and schools, while ensuring that State foundation aid to Westchester schools saw the highest increases in the last decade.

For her extensive legislative work and community service, Senator Stewart-Cousins has been honored with numerous citations and awards from organizations, including: the American Cancer Society, American Civil Liberties Union, the Hudson River Museum, and the National Association of Social Workers. The Senator was also named, "Woman of the Year"
