Marc has decades of experience to bring to the office of Brooklyn District Attorney. He received his Bachelor of Arts in Public Communication from The American University in 1984 and his Juris Doctor from George Washington University Law School in 1987. After law school, Marc began working for District Attorney Elizabeth Holtzman as an Assistant District Attorney in the Kings County District Attorney’s Office. Until 1992, he prosecuted sexual assault, child physical and sexual abuse, and domestic violence cases as a trial assistant in the Sex Crimes and Special Victims Unit.
In 1992, Marc began work as an Assistant Prosecutor with the Monmouth County Prosecutor’s Office, Freehold, NJ. There he became Director of the Sex Crimes and Child Abuse Unit, where he prosecuted high profile child abuse and sexual victimization cases. He has lectured throughout the tri-state area on a number of criminal justice areas. He also served on the New Jersey Sexual Assault Protocol Council, which completely revamped the way sexual assault cases were being investigated statewide.
In 2001, Marc joined the Trenton-based law firm of Kamensky Cohen & Associates as a senior litigation attorney. There, he handled civil and criminal matters before federal and state courts throughout New Jersey, and specialized in cases where children had been sexually victimized in their schools and churches.
Marc returned to the Kings County District Attorney’s Office trying felony sexual assaults as a Senior Assistant in 2006, before moving to the Homicide Bureau. District Attorney Charles Hynes then appointed him Chief of the Major Narcotics Investigations Bureau where he supervised all Assistant District Attorneys, Detective Investigators, and support staff handling the investigation and prosecution of major narcotics and firearms trafficking activities. He was also responsible for prosecution of the Brownsville-based “Wavegang,” and successfully tried and convicted two Wavegang members for murder.
In 2014, District Attorney Kenneth Thompson appointed Marc as Chief of the newly-created Civil Rights Bureau in charge of oversight of all investigations and prosecutions for hate crimes and police misconduct matters. During his tenure, he tried and convicted Mashawn Sonds for the brutal hate-crime beating of a transgender woman in Bushwick. He also tried and convicted Police Officer Joel Edouard for stomping on the head of a restrained civilian in Bedford Stuyvesant, and Police Officer Peter Liang for the shooting death of unarmed civilian Akai Gurley in the Pink Houses Development, East New York.
Marc left the Kings County District Attorney’s Office in June 2016 to open a solo civil rights and criminal defense practice, bringing his years of experience to serving defendants. He is ready to take his decades of experience and apply it to the task of achieving true criminal justice reform in Brooklyn.
Marc lives in Bay Ridge with his father, his husband, Steve, and Jasper, his rescue pup. They have two children: Dylan, a film-maker in Brooklyn, and Julianna, a high school senior.
