Matthew James Troiano

Former Morris County Chief Assistant Prosecutor Matthew James Troiano joined Einhorn, Harris, Ascher, Barbarito & Frost, P.C. as Counsel and Chair of its Criminal Practice Group in November 2018. With great insight as a former prosecutor and a thorough understanding of every stage of the State’s case from the initial investigation through the grand jury process, and ultimately, to trial if needed, Matthew provides clients with legal guidance on very complex situations as well as any criminal matter that can arise in New Jersey. He has seen firsthand what it takes to build a successful case and can offer advice as to how to navigate the criminal process, and if required, take a case to a jury trial.  Based on his experience, he is uniquely situated to help clients who are the subject of an investigation, under arrest, or going through a serious ordeal that requires knowledge of the criminal justice system.

Known throughout New Jersey for his successful prosecution of many high-profile murder cases, Matthew served as a prosecutor since 2006, and with the Morris County Prosecutor’s Office from 2011-2018. During his prosecutorial career, he successfully tried many jury trials in the New Jersey Superior Courts, including murder, aggravated manslaughter, aggravated sexual assault, sexual assault, kidnapping, aggravated assault, arson, aggravated arson, robbery, burglary, weapons, drugs and domestic violence-related crimes. He also appeared before the Appellate Division of the New Jersey Superior Court.

Matthew is recognized by the New Jersey Supreme Court as a Certified Criminal Trial Attorney. Certified attorneys have demonstrated high levels of experience, education, knowledge and skill in criminal law, and have been recognized by their peers as having sufficient skills and reputation in the field of criminal law.

In addition to his experiences as a successful trial attorney, Matthew has been responsible for the supervision and management of many prominent cases, including numerous death investigations, and he has worked collaboratively with attorneys and law enforcement professionals from multiple agencies. These experiences have required him to navigate high-profile situations, which often involve
public scrutiny and extensive interaction with the media.

Troiano’s investigative and trial experiences have been reported in broadcast documentaries including 48 Hours and Deadline: Crime with Tamron Hall. Troiano’s career as a prosecutor began in 2006 with the Hudson County Prosecutor’s Office, where his primary assignment was to the Special Victim’s Unit, handling sex crimes, domestic violence, child abuse and homicide cases. During this time, he tried numerous jury and bench trials before Criminal and Family Judges of the Superior Court.

Matthew joined the Morris County Prosecutor’s Office in April 2011. In early 2014, he was promoted to a supervisory role in the Major Crimes Unit. In July 2015, Troiano was promoted to Chief Assistant Prosecutor, a position he held until he left the Office to join Einhorn Harris. As a Chief Assistant Prosecutor, Troiano was responsible for the legal supervision of the Tactical Units within the Office, including the Major Crimes, Fire-Environmental, Sex Crimes-Child Endangerment, and Domestic Violence Units.

Since 2010, Troiano has been an Adjunct Professor of Appellate Advocacy at Seton Hall Law School in Newark. He also spent 5 years as an Adjunct Professor at Essex County Community College teaching various classes in the area of Criminal Justice. Troiano has been a frequent instructor throughout the state in the area of criminal law and procedure, including teaching in the areas of Interview and Interrogation, Search and Seizure, Police Use of Force and Officer-Involved Shootings, Strategic Motion Practice, and Effective Death Investigations. He served as a liaison to the New Jersey Child Fatality Review Board. In addition, he has served as a panelist or speaker at Seton Hall Law School, Rutgers University, the Criminal Law Section of the New Jersey State Bar Association, the New Jersey Criminal Law Institute, and the New Jersey Association for Justice. Upon graduating from law school, Troiano served as a law clerk to the Honorable Michael R. Casale, J.S.C. (Ret.), Essex Vicinage.
