    If anybody were able to open up a dictionary and search for the definition of professionalism, don't be surprised to see David Barry's picture right beside it. A marksman within his field of expertise, David was able to pinpoint the target areas within my case to make the transition of a difficult outcome to an easy ride off into the sunset. David's nonchalant approach to hectic scenarios is a quality that every lawyer must have to assure total comfortability amongst their clients

    I wish I had more than 500 characters to describe what an amazing attorney and human being Mr. Gann is. After I unsuccessfully resolved a traffic issue on my own (an unknown person using my plate illegally), and contact with the responsible government offices provided no relief, I contacted Mr. Gann, who agreed to attempt to help me. Mr. Gann appeared in court on my behalf and successfully resolved the issue that same day. I would recommend him to absolutely anyone in need of legal assistance

    Phil is a one of a kind lawyer. He put his heart, relentless time and effort into my situation. He was always available, loyal and really busted his behind.

I must have worded questions 9 different ways multiple times. He always gave me a truthful answer, never dodged my calls or emails. 5

    I thought I would never see my family again. Then, I was introduced to Marc. I knew from the first meeting that he was special and could and would help me. Marc was always a quick phone call away and answered my questions professionally and compassionately. I felt like I was his only client. I did everything Marc told me to do. With his help, my misdemeanor was dropped to a violation. I have been home now for a year and have Marc Gann to thank!

He displayed patience, understood my situation and answered all of my questions with care and understanding. I am extremely happy and pleased with the results I received!

    Being the young dumb kid I am, I had gotten into some trouble with the law and had no one to turn to or any idea how I was going to fight this. I met Mr. David Barry on one of my court dates and knew he was the one to help me get out of this mess I created for myself. He was extremely professional and understanding of my situation as well as willing to work with my budget to come up with a payment plan I could afford. No matter what your situation is, Id highly recommend him. Thank you Mr Barry

    Gerard C. Mc Closkey is equipped to handle all types of criminal charges, including those that may seem minor. Gerard C. Mc Closkey is concerned with protecting your rights and has the resources and tenacity to help secure the most preferable outcomes possible. Of course, no criminal defense lawyer can promise an acquittal or a favorable plea bargain; making such guarantees is unethical. However, the nature of the legal system is such that prosecuting attorneys often have enormous advantages over defendants. Many of those accused of crimes lack the resources to hire competent legal representation and because district attorneys possess significant leverage over defendants, many defendants end up negotiating away their rights and signing onto plea bargains that will haunt them for years. Gerard C. Mc Closkey evens the scales. As a former Assistant District Attorney he is never intimidated by the prosecution. He will investigate your case and find the flaws in the prosecutions theories, find witnesses and arrange expert testimony on your behalf, and do everything possible to achieve preferred outcomes.
