Working with David was a great experience. He was very knowledgeable and was easily available any time I had a question. He was very dedicated to my case. I would highly recommend and definitely use David in the future.

Hired Attorney David Barry Esq.

I am extremely impressed with the service, attention and detailed work that David Barry put into my case. Not only did he keep me abreast as to what was going on but was honest and helpful with his information. Thankfully, Collins, Gann, McCloskey, & Barry were able to get my case dismissed. I could not have asked for better representation.

Hired Attorney David Barry Esq.

I had received a traffic ticket and was worried about all the things that could go wrong from losing points to increases in insurance premiums. David came to the rescue and put my mind at ease when he told me he could reduce my ticket. Sure enough he was successful and I am so thankful! He was professional, responsive, and took the time to explain all the details of the case with me. I recommend David and his law firm if you want results!

Hired Attorney Rick Collins

I don't know where to begin but Mr Collins saved not only my life but my family's life as well. There would have been no other attorney in the country that would have gotten me out of the situation I was in. I got caught up in a multinational, multi-agency investagation including Scotland Yard and homeland security No one else would have been able to explain the situation to the agents in a manner in which they would have understood. I have never even heard in my life such a thing as a attorney stopping a federal investigation into someone with just a few phone calls. I have dealt with several attorneys in my life but by far Mr. Collins is hands above the smartest one I've ever dealt with. I never will be able to thank Mr. Collin enough for what he has done for my family and I. He really is a God sent, I am still amazed but what he did. I can't recommend him enough dealing with any case that you would have

Very please with Mark Gann and especially David Barry who initially interviewed me about my case and showed so much concern that it immediately sparked my interest in this firm. Then Mark came along and help my case and told me exactly what is going on step by step and the final expectations. Mark always returned my calls in a timely manner and ease my mind on any concerns I had. Thanks guys for your professionalism and understanding. Now this is my law firm.
