Madeline Singas was inaugurated as the 15th elected District Attorney of Nassau County in January 2016.  As DA, she serves as the county’s independently-elected chief law enforcement officer, ultimately responsible for all criminal and minor offense prosecutions that occur within Nassau’s various courts, as well as their appeal to higher state and federal courts.  Presiding over the nation’s 32nd largest criminal jurisdiction, DA Singas manages a legal, investigative, and support staff of nearly 400, an annual office budget of nearly $40 million, and over 30,000 case prosecutions each year.   

Since taking office, DA Singas has overseen the steady enhancement of criminal justice services to the citizens of Nassau County.  Using advanced investigative techniques, collaborative partnerships and intelligence-based prosecution models, she has focused the skill and resources of her office towards combating narcotics and weapons trafficking, career criminals, violent gangs, and corruption in government.  She has dedicated unprecedented resources to battle the pandemic of heroin and opiate abuse, prioritizing education and treatment for victims of the drug trade while simultaneously attacking the supply chain through massive take-downs of organized distributors.  Using economics against the major traffickers, DA Singas has invested substantial amounts of legally seized drug money into local treatment facilities in order to reduce addiction and therefore demand.          

DA Singas has also made it a mission of her office to eradicate corruption in Nassau County, utilizing the same bevy of tools and resources that she would against a sophisticated organized crime ring. Indeed, a hallmark of her administration has been massive in-depth probes and take-downs of corrupted government officials and their associates, accompanied by substantial and repeated calls for enhanced transparency and oversight for government operations.

With more than two decades of service as a courtroom prosecutor in both Queens and Nassau Counties, DA Singas now combines her practical experience with 21st Century data-driven law enforcement and crime prevention strategies.  She has built Nassau’s first-ever Crime Strategies Unit, a cooperative analytical effort with the National Guard, the Nassau County Police Department, the Nassau County Sheriff’s Department, and other local and regional partners, to detect, target, and incapacitate Nassau’s biggest “crime-drivers.”

As a leader in her profession, DA Singas was appointed by Chief Judge Janet DiFiore to the New York State Commission on Justice for Children as well as to the New York State Justice Task Force, where she has helped shape statewide policies on attorney misconduct, wrongful conviction safeguards, bail reform, and the streamlining of court operations.  She is an active member of Prosecutors Against Gun Violence (PAGV), an independent coalition of prosecutors from jurisdictions across the United States working towards prosecutorial and policy solutions to the national public health and safety crisis of gun violence.  She also serves on the board of directors of the New York State District Attorneys Association and has served on the New York State Bar Association’s Special Committee on Reentry, which worked on a broad array of recommendations for the successful reintegration of incarcerated individuals into society post-release.  In 2014, she led a legislative task force that re-wrote New York’s Criminal Procedure Law to allow the introduction of photographic line-ups into evidence at trial.  

The daughter of Greek immigrants, DA Singas grew up in Astoria.  She is a graduate of the Bronx High School of Science, Barnard College, and Fordham University School of Law.  She lives in Manhasset with her husband and teenage twins.
