    "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.

    "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!

    "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!

    "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.

    "As far as lawyers go, Mr. Sachs is an "11 out of 10""
    WOW, can't say enough about David Sachs, professional, aggressive, knowledgeable and never left me in the dark about my felony DWI case. When I hired Mr. Sachs and his firm I already had a felony DWI conviction and I was sentenced to five years' probation. I came to the firm with my second felony DWI charge and probation violation. Mr. Sachs was able to get me restored back to probation with no jail time. Then I picked up my third felony DWI charge and I thought it was all over for me. However, Mr. Sachs never lets up! I doubted his belief that I could get back on probation and stay out of state prison. But in the end, he delivered! Mr. Sachs gave a very passionate sentencing argument to the judge. I was very moved myself. Because of the Mr. Sachs' loyalty to me and his profession, the impossible was made possible! As far as lawyers go, Mr. Sachs is an "11 out of 10". God Bless.
