State Senator Jason Lewis proudly represents the people of the Fifth Middlesex District of Massachusetts, which includes the cities and towns of Malden, Melrose, Reading, Stoneham, Wakefield, and parts of Winchester. He has been a leader in shaping public policy on a range of issues important to his district, region and the state, including healthcare, education, and economic opportunity for all.

Senator Lewis was elected to the State Senate in 2014 following five years serving in the Massachusetts House of Representatives. As the Assistant Majority Whip, he is part of the leadership team that sets the agenda and policy priorities for the Senate. He also serves as the Senate Chair of the Joint Committee on Public Health and the Joint Committee on Labor and Workforce Development. He is a member of the Joint Committee on Education, Joint Committee on Healthcare Financing, Joint Committee on Election Laws, Joint Committee on Marijuana Policy, and the Senate Committee on Global Warming and Climate Change. He also co-founded and co-Chairs the legislature’s Prevention for Health Caucus.

Senator Lewis believes healthcare is a human right and he has led efforts to improve the quality of care and contain healthcare costs by focusing on prevention and public health. He has championed reforms to the state’s education financing system in order to ensure that all children have access to a high-quality public education. And he has been a forceful advocate for increasing economic opportunity and fairness for poor and working families.

Senator Lewis was born in South Africa and came to the United States with his family when he was twelve years old. His experience growing up in a segregated society — as South Africa was under the racist apartheid system at the time — grounded him with a deep sense of social and economic justice, and he has been outspoken on issues of racial, gender, and LGBTQ equality.

Senator Lewis attended public schools, and, with the help of merit scholarships, graduated from Harvard College with a degree in Economics. He also earned an MBA degree from Harvard University.

Prior to entering public service, Senator Lewis had a long track record of accomplishment in the private sector, having helped build two successful software companies. He began his career with McKinsey & Company, a global management consulting firm. He held a number of senior management roles with RSA Security, a Bedford-based software company that is now part of Dell EMC, and later was the Senior Vice President of Marketing at Endeca Technologies, a venture capital-backed software company in Cambridge that is now owned by Oracle.

Senator Lewis and his wife, Susan, live in Winchester with their two daughters, Sophie and Jessie. Susan is a middle school science teacher and also serves on the Board of the Winchester Multicultural Network.

Senator Lewis is an elected member of Winchester Town Meeting. He previously served on the Winchester Finance Committee, the Winchester Master Plan Steering Committee, and the Board of Trustees of the Winchester Foundation for Educational Excellence.
