Jason Seidman

Attorney Jason A. Seidman spent five years as a prosecutor, attaining a level of know-how that is invaluable to his criminal defense practice — and his clients — today. “I know how prosecutors think,” he says. “That can be incredibly valuable now, in either trying to get a better plea offer or in trying to find a strategy to win at trial because you know that the prosecutor is thinking like a prosecutor and you can slip some defense attorney strategies in there that they never see coming.”

As a prosecutor, Attorney Seidman was involved in a high-profiled cold case murder that was brought back to life by DNA evidence 30 years after. The case was a homicide of a 15-year-old prostitute. Attorney Seidman was part of the team that secured the conviction of the killer following a five-week trial that involved 30 witnesses.

Another highlight was his involvement in the investigation and prosecution of a 24-defendant racketeering case involving rival subsets of the Bloods street gang, the G-Shine Bloods and the Nine Trey Bloods, which were engaged in a turf war that resulted in the death of an innocent man killed by a stray bullet.

Attorney Seidman recently had a jury trial wherein his client was facing years behind bars and parole ineligibility since it was a gun case. Attorney Seidman secured a NOT GUILTY verdict after the jury deliberated for thirty (30) minutes. 

Attorney Seidman’s current practice focuses on criminal law with a strong emphasis on felony-level cases. He has achieved numerous positive outcomes for clients, including dismissal of a case where his client faced up to 10 years in prison involving a gun that the client didn’t know was in his bag and was detected by airport screening. Attorney Seidman has also been successful at having a number of his clients who were first-time offenders admitted to the state’s Pretrial Intervention Program (PTI).

During his time as an Assistant Prosecutor, Attorney Seidman had some high-profile achievements. During the first 3½ years of his tenure there, he became a member of the trial team that handled street-level drug-distribution cases. These cases ranged from possession with intent to distribute marijuana and cocaine all the way up to first-degree distribution and possession with the intent to distribute PCP. In addition to prosecuting drug cases, he also supervised the office’s Drug Court Unit, which aspires to help people beat their habits. He then moved to a trial team, and finally became the director of the Gangs, Guns and Drugs Task Force, a proactive investigative unit that assists the prosecutors. He spent his last 1½ years in the prosecutor’s office in that capacity.

A New Jersey native, Attorney Seidman comes from a family of lawyers. His mother and grandfather were both prosecutors, and his great-grandfather was a trusts and estates attorney. He received a B.A. in government and law from Lafayette College in 2005 and earned his J.D. from the University of the District of Columbia in 2009.
