Judge Arthur M. Diamond: Professional Background and Legal Expertise

Biography

The Hon. Arthur M. Diamond (Ret.) served as a justice on the Nassau County Supreme Court in the 10th Judicial District of New York. Diamond was elected to the bench on November 4, 2003. He retired in 2020.


Diamond held assignments as the supervising judge of guardianship matters (2016 to 2020).


Prior to his election, Diamond was senior vice president and general counsel for Curran & Connors, a graphics firm in Hauppauge. Before that, he sat as a judge on the Nassau County Court (1999 to 2000) and a village prosecutor for the Village of Manorhaven (1994 to 1996).


Diamond earned a B.A. in political science from Rutgers University in 1974. He then completed a J.D. at Hofstra University, Maurice A. Deane School of Law, in 1978.


After graduating from law school, Diamond began his legal career as an assistant district attorney with the Nassau County District Attorney’s Office. He remained there for the next seven years, rising through the ranks to become deputy chief of the Trial Bureau. Then, in 1986, he entered into business, where he remained for the next six years before returning to the law, this time as a personal injury and criminal defense attorney at Fishkin & Pugach in Garden City.


His memberships have included the Nassau County Bar Association and Guardianship Access New York. He has lectured extensively on the subject of evidence for the Nassau County Bar Association, the New York State Bar Association, the New York County Lawyers Association, and the New York State Judicial Institute, and he has co-edited the 2013 revision of the Bench Book for Judges.


He is a recipient of the Gold Gavel Award from the Nassau County Bar Association (2021).
