    "I would recommend David's services to anyone."
    I was recently represented by Mr. David Sachs. I found him to be very professional and competent. He showed great confidence in his ability to win my case. He made me feel at ease. And I would recommend his services to anyone. He is a great attorney!!!!!!!
    - David M.
    "They are winners!"
    The law firm and partners handled my case like pros. You see my overall rating of these men. I'm an excitable man I guess it was better not to inform me about some things so I didn't act out at the time they wanted me to stay calm. Outstanding, you go lawyers.

    "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.

    - Karina
    "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.
    - Former Client
    "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.
    - Kara
    "Through their hard work, I was able to have my case dropped from a potential class 1 misdemeanor to a class 3 violation with a sealed case which will never have any bearing on my future."
    David Sachs and the lawyers at Proto, Sachs & Brown, LLP are the best criminal lawyers in Westchester County. Each lawyer in the firm are top-rated as I had the opportunity to work with each of the 3 attorneys.
    - Robert C.
    "In addition to answering all my questions, I felt as though he understood my concerns and was ready to fight for me."
    I hired the law firm while searching for an attorney who specialized in DWI cases. I had a pending case with the Bronx Probation Department and felt hopeless. I called the office and within an hour received a response from Andrew Proto. I explained my situation in great detail and for the first time since my arrest, someone was on my side! In addition to answering all my questions, I felt as though he understood my concerns and was ready to fight for me. I can't tell you enough how refreshing it was to have someone in your corner, especially since my previous attorney wouldn't give me the time of day. The firm was very professional and extremely knowledgeable of DWI law. Mr. Proto went as far as contacting the Counsel's office for the Bronx Probation Dept. to make his presence known. He wanted to make sure I wasn't being taken advantage of and pleaded my case. Whenever I called the firm they responded immediately, even if I reached out multiple times a day. I tend to over analyze details and Mr. Proto was very polite and understanding in dealing with me. He reassured and kept me informed throughout my horrible ordeal. I felt at peace knowing Mr. Proto was handling my case; I had not felt peaceful in a long time. To this day, although the case is settled, my lawyer continues to reach out to the Bronx Probation Dept. showing he is ready to fight on my behalf. I highly recommend these guys, they get the job done.
