From the moment I met Gerard McCloskey in his office ,my gut told me that he was an excellent lawyer, professional and extremely knowledgeable. I was falsely arrested for a felony and maintained my innocence. Gerard guided me through the legal process, which I had very little knowledge of, was always available to answer my questions ( I had many) and was sympathetic to my situation. He told me that he would get my case dismissed and he worked diligently to accomplish just that. I would advise anyone who needs a criminal lawyer to hire Gerard. Not only is he a fantastic attorney but he put me at ease with his calm nature and expertise.

David won my case. Case dismissed. From the start he was on point, figured out faults with the evidence and immediately used it to our benefit. A dismissal is a rare feat that he achieved due to his knowledge, determination and diligence. I would recommend David to anyone who is trying to find a competent attorney for their case.

Mr. Barry is a professional with what he does. I was arrested due to false report and experienced issues with work. Mr. Barry was able to explain to me my rights and connect me to the proper resources. He also took the time to provide me support during a stressful situation. I am extremely grateful for the support and time Mr. Barry took to explain to me my disposition paper.
