    "It was also obvious to me that the judges and even the prosecutors know and liked Andrew which I believe made him lawyer much more effective and successful in my case."
    About a year ago I met with Andrew Proto and hired his firm, Proto, Sachs & Brown, LLP to handle my criminal case. Andrew was able to work out a deal with the prosecutor to have my criminal charges dismissed and my court record sealed. It was also obvious to me that the judges and even the prosecutors know and liked Andrew which I believe made him lawyer much more effective and successful in my case. I really appreciate his service and the firm.

    "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.

    "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!!!

    "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!
    - Laura and Todd D.
    "Their staff was always in contact to provide me with an update at all times."
    Both, David Sachs and Andrew Proto demonstrated strong character, punctuality, support and constantly searching for all options to win my both cases, and they made it possible.
    - Adela L.
    "Outstanding lawyers. I have worked with them twice and they know what they are doing."
    I have worked with Keith Brown and he always took the time to answer my questions. He always had a plan for me and explained everything clearly.
