About me

Matheu D. Nunn joined Einhorn Harris Ascher Barbarito & Frost, PC in December 2011. He came to the firm after serving as an Assistant Prosecutor for the Morris County Prosecutor’s Office.  In 2012, Matheu was appointed to serve as the Prosecutor for Morris Township.

Mr. Nunn has a passion for the law and has a diverse background which serves his clients well.  Currently he is studying for his LL.M. in Insurance Law at the University of Connecticut School of Law.  His background as a prosecutor provides him with knowledge in criminal and municipal law as well as working with DYFS and Domestic Violence cases. 

A prolific public speaker while at the Morris County Prosecutor’s office, Matheu D. Nunn has given presentations on Family Law and Privacy, Cyber-bullying, The Law of Interrogation and Appellate Law to name a few.

Mr. Nunn is a member of The 200 Club of Morris County; a local philanthropic organization which focuses its efforts on providing financial support to the families of fallen police officers and firefighters.  He also offers his time as a “Volunteer Judge” for Moot Court competitions at Rutgers School of Law and Morris County High Schools.

Mr. Nunn received his Bachelor of Arts in Political Science from the University of Delaware and then his JD from Rutgers School of Law-Camden, where he earned "with Honors" distinction and was an editor of the law review. During his law school tenure, he worked in the legal department of ING Direct, and completed externships for the Honorable Joseph A. Falcone, J.S.C., and the Morris County Prosecutor’s Office.

Following law school, he completed two clerkships. The first for the Honorable B. Theodore Bozonelis, the Assignment Judge for Morris County; the second for the Honorable Jack M. Sabatino, a judge at the Appellate Division of New Jersey.  At the conclusion of that clerkship, in September 2009, Mr. Nunn joined the Morris County Prosecutor’s Office, where he worked as an Assistant Prosecutor in the Appellate Unit and Major Crimes Unit prior to joining the firm.

  • Robert Anthony Bianchi

    I endorse this lawyer. Mr. Nunn is an excellent attorney with a great pedigree as an attorney. When I was Morris County Prosecutor, Mr. Nunn was one of my Assistant Prosecutors. He is a skilled lawyer and advocate, great on the law, and a great writer. He also has the unique ability to combine those legal research skills, with great presentation skills in the courtroom (a unique combination, in my experience). He is a tough advocate, but is always professional in his approach. No worries using this attorney for your matter. You will be well served.
