Jennifer served the People of Nassau County in that position for over five years while she prosecuted serious felony offenses, conducted wiretap investigations and worked closely with detectives, police officers, and federal agents.

Jennifer’s tenure as a prosecutor began as most prosecutors do; in District Court where she handled traffic violations, Driving While Intoxicated (DWI) related offenses and many other misdemeanors, including assault, aggravated harassment, reckless endangerment, sexually-based offenses, drug-related offenses and larceny related offenses, successfully trying several of them to verdict and conducting many evidentiary hearings in the process.

Rising quickly, Jennifer was then promoted from District Court after only one year and was assigned to the Special Victim’s Bureau, where she exclusively prosecuted domestic violence cases and tried several of them to verdict.

Jennifer was then promoted again to the Grand Jury bureau where she presented numerous cases to the Grand Jury and secured indictments in nearly every case. In addition, during that time, Jennifer assisted police officers and detectives in determining which crimes with which to charge defendants and also acted as an advisor regarding complex legal situations. Jennifer also handled all requests by detectives and police officers for search warrants in matters including kidnapping, homicide, drug sales and vehicular manslaughter.

Again rising quickly, after approximately one year, Jennifer was promoted to the elite Organized Crime and Rackets Bureau where she worked closely with State and Federal Agents while she investigated and prosecuted cases involving organized crime, sexual abuse of children, child pornography, drug manufacturing and distribution, violations of the New York State Tax Law, witness tampering, gambling-related offenses and enterprise corruption.

During that time, Jennifer worked closely with the United States Attorney’s Office for both the Eastern District of New York as well as the Southern District of New York. While assigned to the Organized Crime and Rackets Bureau, Jennifer conducted numerous investigations involving court-authorized eavesdropping warrants (wiretaps) on approximately seventeen different phones, earning her a multitude of awards from the Federal Government, which include the “True American Hero Award” from The Federal Drugs Agent’s Foundation, the award for “Superior Performance in the Field of Drug Law Enforcement” from The Federal Drug Agents Foundation, an award for “Professionalism and Dedication” from The Organized Crime Drug Enforcement Strike Force Financial Investigations Team and award for “Hard work and Dedication” from the United States of America Department of Justice. As a defense attorney, Jennifer utilizes her many years of experience as a prosecutor to assist her clients in every way possible.
