Law Firm Overview

Collins Gann McCloskey & Barry PLLC is a dedicated team of Nassau County criminal lawyers defending clients charged with all types of criminal offenses.
With a combined 60 years of experience in the criminal courts as both prosecutors and defense attorneys, we understand the challenges that face criminal defendants. We also are acutely aware that a criminal conviction can irrevocably damage a person’s record, employment opportunities, personal freedom, and future.

Our dedicated team begins by thoroughly investigating what happened, then we explain the applicable law and advise you on your options for your case. Our mission is to get your case dismissed or to have you acquitted. When this is not possible, we use all available legal means to minimize the consequences for you. If a plea agreement is offered, we evaluate the full impact of the proposal — including sentencing options and the effect on your criminal record and advise you accordingly. Clients from all over the country have benefited from the combined 60 years of experience and expertise of our criminal defense law firm in Nassau County, N.Y.
