    "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!

    "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!!!

    "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!

    "I was lucky to have such an open and compassionate lawyer."
    The firm was a big help in my DWI case in White Plains. We appeared in Court together and they always took time to explain my case and all of my options. My lawyer even gave me his e-mail address and responded to my questions on weekends. I was lucky to have such an open and compassionate lawyer. I didn't know my lawyer from anyone when I found him on the internet but now I feel comfortable calling him anytime. He also helped me with my child custody issues that keep coming up. I would recommend you call him with any questions.
    - 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.
    - Matthew B
    "With me every step of the way"
    Keith Brown and Andy Proto are bothe very caring, knowledgeable and attentive attorneys. They were with me every step of the way through a very tough child custody case. On first meeting, Keith told me we would come out victorious and he held true to that. Their strategy was explained clearly and decisively throughout and was available at any time to answer any questions or concerns I ever had. When it came down to crunch time, they worked countless hours even outside of their regular business hours to get the results we want ed and needed. I would recommend this firm and these attorneys to anyone in need.
