    "Andrew contacted me to discuss and followed through 100% on everything he said."
    Gave them all necessary info about my case using their website. Andrew contacted me to discuss and followed through 100% on everything he said. I did not have to personally appear in court. Andrew handled everything for me with the Traffic Court judge. Ticket I had was reduced to a small fine and no points on my license keeping my record clean and avoiding possible increased car insurance cost. Will recommend Andrew and his firm to any family members & friends in need of legal council.

    "The best part was anytime I needed to speak with Andrew, he was available and always offered to answer my questions even on weekends."
    Andrew Proto is the best!! He helped me on my DWI case in Harrison New York so much. All the other lawyers I spoke to were doom and gloom. Andrew told me everything I needed to know about my case and was very aggressive against the DA. I was so comfortable in court with him. The best part was anytime I needed to speak with him he was available and always offered to answer my questions even on weekends. Thanks to him and his office for the help!!!

    "I had spent three years working hard for 0 points on my license, so the small investment in this firm for a good defense seemed a good idea."
    The interaction with the firm is a 10/10 with prompt, precise and on point responses. Obviously this firm knows how to navigate the court system and in my case it was a $$$$ saver for my speeding violation, saving me points and I am sure a few digits on my

    "The result was everything I wanted no criminal convictions and most of the charges were just dismissed."
    I am not happy about my DWI, but the firm was perfect in helping me get through the case. They explained everything to me and took the time to answer my questions. The result was everything I wanted no criminal convictions and most of the charges were just dismissed. What I liked the best was a few weeks after my case was over they took my call and answered the other questions I had. They are really nice guys and a great attorneys. If you have a problem just call. You will not be disappointed.
    - Former Client
    "Fantastic law firm from top to bottom."
    David and Keith were fantastic throughout my case. Their knowledge , thoroughness and compassion was outstanding. Going through a divorce with small children was the worst time in my life but I was able to get through it with their help. Keith was always fully prepared for court and always had me fully prepared no matter my emotional state. He was hard and focused when he needed to be and always listened to every detail big or small. I wouldn't be where I am today with 2 happy kids if it wasn't for all of the help and hard work from David and Keith.

    "David gave me the feeling that I was going to be well protected in my trumped up, ridiculously racist criminal charges against me."
    After talking to a couple of other area lawyers, this firm seemed more aggressive. I met with David Sachs at my first meeting and he gave me the feeling that I was going to be well protected in my trumped up, ridiculously racist criminal charges against me. Money well spent. David was fantastic. He was able to have my case dismissed by filing legal papers with a court appearance with testimony (not a trial). Judge agreed with his legal opinion and dismissed my case. I can't thank him enough. Also, on one court date lawyer Andrew Proto from the firm appeared on my case which was fine, because I did hire the firm, but what was exceptional about it was that he knew my case just as well as David. In my view, this firm is top notch.
    - Darius L.
    "I would recommend David's services to anyone."
    I was recently represented by Mr. David Sachs. I found him to be very professional and competent. He showed great confidence in his ability to win my case. He made me feel at ease. And I would recommend his services to anyone. He is a great attorney!!!!!!!
