Biography

The Hon. Pierce F. Cohalan is a judge on the Suffolk County District Court in the 10th Judicial District of New York. He was elected to the bench on November 4, 2014.

Cohalan has held assignments as an acting judge on the Suffolk County Court (2018 to 2026). He presided over the Suffolk County Veterans Court, sitting in the courthouse that bears the name of his grandfather, the Hon. John P. Cohalan, Jr.

Prior to his election, Cohalan was the chief deputy commissioner of public safety for the Town of Islip, a position to which he was named in 2013.

Cohalan earned a B.A. from Lehigh University in 1989. He then completed a J.D. at Hofstra University, Maurice A. Deane School of Law, in 1994. Cohalan has also received an M.B.A. from Columbia Business School (2006).

He is licensed to practice in New York (1996).

After graduating from law school, Cohalan began his legal career as an assistant district attorney with the Suffolk County District Attorney’s Office. He served in that capacity until 2001, at which time he joined an engineering company. Then, in 2006, he was hired as the town attorney for the Town of Islip. He remained there for the next year, eventually leaving to enter into private practice.

Cohalan was a resident of Great River, New York, at the time of his election. He holds the distinction of being the sixth member of his family across four generations to become a judge. He is also the first judge to captain a ferry boat on the Great South Bay. A veteran of the United States Army, Cohalan was deployed to Afghanistan in 2012. He served as a legal advisor on the Combined Joint Special Operations Task Force.

He is registered as a Republican.
