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.

Once I met with Jennifer I knew she would be the best lawyer for me! She took my case seriously and always kept me updated. I also had an amazing result on my court case which I wouldve never thought couldve happened. I couldnt ask anything more from a lawyer!

My husband and I hired Jennifer Mazzei to file an immigration petition. Jennifer was extremely helpful, approachable and down to earth since day one, she always took the time to explain every detail and clarify every doubt. I reached out to her several times, and she was always quick at replying and willing to answer every question we had. When she was gone for personal reasons, it was easy to reach out to Jim Polk who was extremely helpful as well. Jennifer made the process very easy for us. Our petition was approved in 11 months without any issue, and we would surely recommend her to anyone in need of an immigration attorney.

Ms. Mazzei is very bright, an excellent attorney. We hired her to defend my son on a misdemeanor and to me, his dad, it didn't look too good. But she showed up in Court totally prepared and somehow managed to get the charge dismissed (after probation). Her results exceeded our expectations. Hopefully we never are in this position again, but if we were, we'd hire her again in an instant.

Jennifer treated me with the utmost respect and dignity during my time of crisis. She is reliable and dependable. Her professionalism, understanding, and compassion are a rarity in most attorneys, but Jennifer had all 3 qualities, making her a unique criminal defense lawyer. I would highly recommend Jennifer to anyone in need.

My husband and I hired Jennifer for help with our petition for my husband's green card. The paperwork required for the green card can seem overwhelming, but she made it all so clear, simple, and easy. She provided us with detailed lists of the paperwork we needed to gather, which made the whole process so much easier for us. She was willing to meet with us as many times as was needed to go through everything with us. We appreciated her dedication to organization and her expertise advice. She is very professional, yet very personable and down to earth. I highly recommend her!

My wife and I just had a preliminary consultation with Ms. Jennifer Mazzei and Mr. James Polk. We were very impressed with each of them. . They took their time to listen to us and were very thorough in explaining the hurdles and limitations of our situation. And are honest counselors. We recommend them to all who read this. It's very hard to find lawyers like them. I met many lawyers in my life and these two touched us in a special way.

During the consultation, Jennifer was very informative, very thorough. After talking to other attorneys, her professionalism and detailed approach during the consultation, convinced me she was the right representative for my case. I highly recommend Jennifer.

I had an issue going back 30+ years, I spoke with 5 other lawyers and not one could see my point. I had a brief phone call with Jenn, she was able to acquire documents that were needed, saw my concerns, and proceeded to work on my case. Her sharp mind, acute eye and experience in the practice of law, gained me the victory I have been chasing for decades. She was prompt to return phone calls, friendly and polite. I am completely grateful.

Jen had initially helped me file my green card petition (based on my marriage) in 2015. She was very thorough and I had no trouble getting my conditional green card. Unfortunately, my husband and I parted ways 2 years later and I found myself reaching out to Jen again, this time from Arizona, where my husband and I had moved to since getting married. Jen continued to be very helpful and quickly returned all of my calls. Long story short- I moved back to NY and filed for the removal of condition on my GC alone with Jen's help. Both her and Jim felt confident in the likelihood of a positive with my case and provided me with some peace of mind. It has been a long and trying year but I am happy to say the petition for removal of conditions on my green card was approved a week ago, big thanks to Jen! She will be the first person I will turn to for legal advice in the future. I highly recommend her to anyone in need of legal help. Not only is she highly efficient, meticulous and an experienced professional, but also a compassionate person.
