    "David's professionalism put me at ease and I felt confident in his ability to represent me during my court appearance."
    David was very knowledgeable yet also pragmatic and focused when discussing the outcomes surrounding my case. He was able to reach the best deal for me, getting my 6 point traffic ticket dropped to NO points and will NOT be reported to the DMV. He's affordable, and it was immediately obvious to me that he is not concerned about price gouging. David's professionalism put me at ease and I felt confident in his ability to represent me during my court appearance. Everything about the process felt organized and well-managed, and I have no reservations recommending his services.

    "Each lawyer in the firm is very professional. We had complete confidence in them when we retained them for our son's felony drug case."
    David Sachs and the lawyers at Proto, Sachs & Brown, LLP are the best criminal lawyers in Westchester County. Each lawyer in the firm is very professional. We had complete confidence in them when we retained them for our son's felony drug case. Originally we had a different lawyer handling the matter but we felt that the case was headed in the wrong direction as the former lawyer recommended that our son plead guilty to a felony. After we hired them they immediately developed a clearly laid out a strategy and approach to the case and they made us feel at ease. We finally had great lawyers fighting on our son's behalf. Ultimately, our son did not have to plead guilty to a felony or even a crime! Mr. Sachs was able to obtain an ACD dismissal and now our son will not have a criminal record and his plans to become a CPA will not be derailed!!! Thank you soooooo very much Proto, Sachs & Brown, LLP!

    "As far as lawyers go, Mr. Sachs is an "11 out of 10""
    WOW, can't say enough about David Sachs, professional, aggressive, knowledgeable and never left me in the dark about my felony DWI case. When I hired Mr. Sachs and his firm I already had a felony DWI conviction and I was sentenced to five years' probation. I came to the firm with my second felony DWI charge and probation violation. Mr. Sachs was able to get me restored back to probation with no jail time. Then I picked up my third felony DWI charge and I thought it was all over for me. However, Mr. Sachs never lets up! I doubted his belief that I could get back on probation and stay out of state prison. But in the end, he delivered! Mr. Sachs gave a very passionate sentencing argument to the judge. I was very moved myself. Because of the Mr. Sachs' loyalty to me and his profession, the impossible was made possible! As far as lawyers go, Mr. Sachs is an "11 out of 10". God Bless.

    "Definitely the cream of the crop!"
    Mr. Proto is compassionate, professional, and knowledgeable. I was extremely satisfied with the outcome. He delivered what he promised to do. I highly recommend Mr. Proto and his staff.

    "He defended me successfully and I was found not guilty. I am grateful to Andrew for seeking and defending justice."
    Andrew defended me in a serious traffic violation of which I was not guilty. He kept me informed at all times and was knowledgeable and responsive. Notwithstanding that the judge would not accept a plea bargain for this offense as a matter of policy, Andrew requested a trial. He defended me successfully and I was found not guilty. I am grateful to Andrew for seeking and defending justice. I would recommend him highly.

    "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

    "Outstanding lawyers. You have got to talk to them!"
    The firm helped me out in Yonkers, NY with a drug arrest. I thought all was lost and my wife was really annoyed with me. My lawyers kept everything under control and really put my mind at ease. They explained everything and even answered my frantic questions on a Saturday!! They are the type of guys that makes you feel good and knows what they are talking about. Its like everyone knew my lawyer in court and my lawyer was always prepared much more prepared than the DA. They worked everything out for me and all I had to do was stay out of trouble for a few months and the case was dismissed. Just like that dismissed. I wrote this review because I called the firm months and months later and even though I wasn't calling to hire the firm for anything they took the time to talk to me on the phone like a friend. If you don't know what lawyer to call you need to talk to Proto, Sachs & Brown, LLP!! They are great!

    "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.
