About Jennifer
Biography
Jennifer Mazzei, is a graduate of Hofstra University School of Law and practices in the areas of criminal defense and immigration. Prior to co-founding The Law Offices of Mazzei & Polk, L.L.C., she was an Assistant District Attorney in the Nassau County District Attorney’s Office for over five years. During that time, she prosecuted felony and misdemeanor crimes, conducted wiretap investigations, worked closely with detectives and police officers and assisted in several federal investigations.
Jennifer began her career 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 and drug related offenses, trying several of them to verdict and conducting many evidentiary hearings in the process.
Rising up the ranks 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 for approximately one year and tried several of them to verdict.
Jennifer was then promoted again to the Grand Jury warrant rotation 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 what crimes to charge defendants with and advised them on how to handle certain legal situations. Jennifer also handled all requests by detectives and police officers for search warrants in matters including homicides and vehicular manslaughter.
Again rising quickly, after approximately one year, Jennifer was again promoted to the elite Organized Crime and Rackets Bureau where she worked closely with local law enforcement as well as 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. On more than one matter, 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 to prosecute numerous defendants. While assigned to the Rackets Bureau, Jennifer conducted investigations involving court authorized eavesdropping warrants (wiretaps) on approximately seventeen different phones, earning her multiple awards from the federal government's various agencies including the United States Attorney's Office for the Southern District of New York.
