David Benowitz and his firm are the best strategic and compassionate teams you will work with. Mr. Benowitz and his team are diligent and proactive, which is further enhanced by David’s methodic and strategic approach to law. My case was a very complicated and emotionally charged case involving classified information, where I was facing three indictments, two carrying life sentences and one carrying 20 years. Mr. Benowitz utilized a network of lawyers coupled with his own strategy to navigate the case to success! I sincerely recommend David Benowitz quite literally with my life.
