Nathan J. Mammarella, Esquire

Mr. Mammarella’s experience and reputation speak for itself. He is known for his relentless advocacy, creative legal arguments, and willingness to try cases. Mr. Mammarella has experience trying criminal jury trials as well as DUI and Misdemeanor cases throughout the State of New Jersey.

Mr. Mammarella’s professional training also sets him apart from most attorneys who represent individuals charged with DUI. He is one of less than 100 New Jersey criminal defense attorneys who have completed the New Jersey Operator’s Training Course for the Alcotest 9510, which is the breath machine used by the State to prosecute defendants charged with DUI.

Mr. Mammarella is also in the process of being certified by Chemistry and the Law (CHAL) Division of the American Chemical Society (ACS) as a Forensic Lawyer-Scientist. This is scientific training covering gas and liquid chromatography (GC-FID, GC-MS, HPLC), forensic drug analysis, and the pharmacology of drug- or alcohol-impaired driving (DUID). Candidates must pass a comprehensive proficiency examination after finishing the required curriculum that teaches attorneys how to read, analyze, and challenge state-run blood, breath, and urine tests the exact same way a forensic laboratory analyst does. Mr. Mammarella’s anticipated proficiency examination date is in October, 2027.

Mr. Mammarella graduated from Rutgers University School of Law (formerly Rutgers School of Law-Camden) and took classes focusing on criminal procedure, trial advocacy, and criminal litigation. He was also heavily involved in the school’s juvenile clinical program. The Children’s Justice Clinic gave Mr. Mammarella a practical knowledge of juvenile offenses, experience in criminal litigation, and provided an opportunity to further develop an interest in helping low-income juveniles and families. He has successfully argued on behalf of clients involved in serious drug offenses, violent assaults, and multiple types of theft and larceny.

Mr. Mammarella was also a member of the prestigious Rutgers Journal of Law & Religion. His writing skills and legal acumen were recognized by his appointment as a Senior Editor of the Rutgers Journal of Law & Religion, which allowed for him to further hone his legal writing and research skills.

Outside of the office, Mr. Mammarella is an avid reader, enjoys history and volunteers at his former High School as a Mock Trial coach.

  I had a great experience working with Nathan Mammarella and would highly recommend him. He was professional, knowledgeable, and easy to work with throughout the entire process. Nathan was able to get my ticket completely dismissed and handled everything for me to the point that I didn’t even have to appear virtually in court. He kept me informed, made the whole situation simple and stress-free, and most importantly got me the best possible outcome. I really appreciate the work he put into my case and couldn’t be happier with the result. If you’re looking for an attorney who communicates well, takes care of his clients, and gets results, Nathan is definitely someone I would recommend.
