    "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.

    "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!!!
    - T.M.
    "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.

    - Patrick
    "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!
    - Former Client
    "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.
    "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.
    - Happy 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.
    - Matthew B
