    "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.

    "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.

    "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.

    "She’s amazing!!!"
    Fenisha Williams handled my divorce and she did a phenomenal job! She was always reachable and most importantly always returned my calls. She’s very knowledgeable and was always trying to find the most reasonable solutions…Having her represent me definitely helped me calm down my anxieties. She’s amazing!!!

    "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!!!

    "David Sachs is a fantastic lawyer and overall good guy"
    When I first spoke to David Sachs I instantly felt confident in his abilities and personal character. Great result in my criminal case. I highly recommend him if you are arrested. He is a fantastic lawyer and an overall good guy!

    "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!
