Law Firm Overview

Collins, McDonald & Gann, PC 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 investigating exactly what happened, explaining the applicable law and advising you on your options in the situation. Our goal 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 available, 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 United States have benefited from the combined 60 years of experience and expertise of our criminal defense law firm in Nassau County, N.Y.
