MaryJane Shimsky

MaryJane Shimsky has been a Westchester County Legislator since February 2011. She represents the County’s 12th Legislative District, which includes the Villages of Ardsley, Dobbs Ferry, Hastings-on-Hudson, and Irvington, as well as parts of unincorporated Greenburgh, including Edgemont and most of Hartsdale.

MaryJane is now serving her fifth full term as legislator. As the elected Majority Leader, she leads the caucus of 16 Democratic legislators and shares responsibility for advancing the caucus' legislative agenda, negotiating with the executive branch of County government, and mentoring junior legislators. She has chaired the Committee on Public Works and now serves on the following committees: Appointments; Environment, Health & Energy; Law & Major Contracts; Legislation; Parks & Recreation; Public Safety; Public Works & Transportation; Rules; and Social Services.

In her time on the Board, MaryJane has distinguished herself by her work on infrastructure, and on the environment and public health. She has chaired the Saw Mill Watershed Advisory Board (SWAB), co-chaired the Bronx River Advisory Board (BRAB), and serves as an ex-officio member of the Westchester County Stormwater Advisory Board. Her long term goal is to control flooding and its worsening effects on our highways and neighborhoods.

MaryJane is perhaps best known for her persistence in advocating for repairs to the recently completed Ashford Avenue Bridge, which links the Villages of Ardsley and Dobbs Ferry, and crosses over the New York State Thruway and Saw Mill River Parkway. When she took office, the span was, according to the State Department of Transportation, the worst County-owned bridge in Westchester. She advocated measures to keep debris from falling onto the highways and paths below, and doggedly fought to insure completion of each step of what became the second-largest bridge construction project in County history.

An advocate for road and bridge repair throughout the County, MaryJane served on Governor Cuomo’s task force to study mass transit options for the Mario Cuomo Bridge, and has worked with Senator Andrea Stewart-Cousins and Assemblyman Tom Abinanti to improve traffic safety in her district, especially along the Saw Mill River Road, Lawrence Street, and Jackson Avenue corridors.

A lifelong environmentalist, MaryJane has fought for a legislative agenda designed to simultaneously reduce pollution and the cost of government. Most recently, she has joined her colleagues in pressing for measures to increase the energy efficiency of County facilities. She has also advocated anti-smoking measures, including raising the age for purchasing tobacco to 21, and regulating e-cigarettes the same as tobacco products.

MaryJane has been a leader in Westchester County’s fight against opioid addiction. In 2017, she sponsored the law authorizing Westchester County’s lawsuit against opioid manufacturers. She has advocated to require chain pharmacies to provide pharmaceutical takeback programs to their customers, and to post warning signs about the potential dangers of opioid medication.

MaryJane is a former Vice Chair of the Westchester County Democratic Committee, served as Chair of the Hastings-on-Hudson Democratic Committee for six years, and is a former member of the Greenburgh Democratic Party’s Executive Committee. She spent thousands of hours since 2004 volunteering on Town committees set up in response to the Ridge Hill development, and was instrumental in securing a $5 million settlement to be used for traffic improvements in the area.

A 1982 graduate of Yale University, MaryJane earned a law degree from New York University School of Law in 1985. She worked for four years as an Assistant District Attorney in the Appeals Bureau of the Manhattan district attorney’s office. MaryJane also taught history and geography at Marymount College in Tarrytown before earning a Ph.D. in History from the City University of New York in 2007. As Community Relations Director for Assemblyman Richard Brodsky from 2007-10, MaryJane represented the Assemblyman at events, assisted constituents, and acted as liaison to local governments.

MaryJane grew up in Scranton, PA. She and husband, David Agosto, have two grown children who attended the Hastings-on-Hudson public schools.
