    Andrew Proto and his team are excellent
    Andrew Proto and his team are excellent: effective, efficient, easy to work with.

Thank you, Andrew!

When an urgent issue came up, he answered my call after hours and immediately stepped in to contain the situation, which meant more to me than I can express. He was calm, reassuring, and took the time to explain everything in a way I could understand. Throughout the entire process, I truly felt supported and knew he had my best interests at heart. Andrew is not only highly knowledgeable, professional, and responsive but genuinely cares about his clients. I would confidently recommend him to anyone needing an attorney they can trust.

    Andrew Proto represented me in a criminal case. I was very lucky to have found such an excellent lawyer. He was by my side throughout the process and was available whenever I needed him. The outcome of my case was what I was hoping for. I could have gotten prison time; instead, he negotiated probation.

    He got my case completely dropped
    Andrew, I can’t thank you enough! Mr. Proto is by far the best attorney I have ever met. He handled my DWI case very well as he displayed professionalism and efficiency. He presented me with options and offered solutions and advice. Most importantly, however, at the end he got my case completely dropped into a traffic infraction in the court, which is truly brilliant considering my situation. I highly recommend Mr. Proto as he is an amazing attorney. He works with you, he also responded to all my emails immediately and kept updating me on my case. I’m referring him to all my friends and family. Thank you so much for everything!
    Sorimery Contreras
    If you want someone who will stand by you
    I spoke with a few lawyers before finding Dave (David R. Sachs), and there was a clear distinction between him and the others: patience. The other attorneys I consulted with were quick to interrupt, assumed they knew my situation before I could explain important details, and often gave me negative expectations right away. Dave was different. He truly listened, never rushed me, and most importantly, he made me feel understood. Throughout the process, he was confident, empathetic, and made me feel like I was in safe hands no matter what challenges came up. What stood out most was that Dave wasn’t just professional — he was approachable and kind. He took my panicked phone calls, answered questions with care, and made me feel supported at every step. If you want just a lawyer, you can call anyone. But if you want someone who will stand by you, listen, and fight for the best outcome with integrity, call David R. Sachs. There is no one else I will turn to for anything family law related. Thank you, Dave!
    Angelique Familia
    I strongly recommend this staff (traffic tickets).
    I want to share my experience. I can’t thank enough Proto, Sachs & Brown. They listened to my case and were pretty confident they would resolve my case, and it was resolved. I strongly recommend this staff (traffic tickets).

    He negotiated fairly on my behalf
    I started working with Mr. Keith M. Brown earlier this year to represent me in a residential buy-out settlement. Although this process took longer than anticipated, Mr. Brown was professional. He responded to my emails in a timely manner and kept me informed. He negotiated fairly on my behalf. Thank you.
    Farah Charles
    An absolute rockstar lawyer
    I cannot recommend Andrew Proto from Proto, Sachs & Brown, LLP highly enough. I found myself in an incredibly stressful and time-sensitive situation when my ex-boyfriend filed a last-minute restraining order to prevent me from moving abroad with my dog. With less than four days to prepare for an initial meeting with the judge, I was in urgent need of expert legal help. Andrew was an absolute rockstar from the moment I contacted him. He was incredibly responsive, always available to answer questions and address concerns, and immediately took control of the situation with confidence and clarity. He crafted a strong, strategic response in record time and made sure I was fully prepared for court. During the hearing, Andrew’s professionalism, poise, and command of the facts were nothing short of phenomenal. He presented my case with precision and passion, and it was clear he genuinely cared about achieving the best outcome for me and my dog. Thanks to Andrew’s dedication and expertise, I was able to successfully fight this ridiculous case. If you’re looking for a lawyer who is sharp, compassionate, and truly committed to his clients, Andrew Proto is the one you want in your corner.
    Lizelle Pell
    Highly Recommend Proto, Sachs & Brown LLP
    Being nervous about speaking with the police officer about why they pulled me over, I ended up falling for their explanation. I'm grateful that I came across attorney Andrew Proto as someone who was both professional and helpful. He assured me that I wouldn't have to go to court and that he would handle my appearance. I am very impressed by the outcome and highly recommend Proto, Sachs & Brown LLP. Thank you again, as well as his team.
    GC I
    Fantastic Legal Service!
    Fantastic legal service! Andrew Proto was professional and friendly. The process was simple and the matter was resolved efficiently. I wouldn’t hesitate to use his services again or recommend him to others.
    Matt Coleman
    Strong, supportive legal advocate
    I can't thank my attorney David R. Sachs enough for the incredible support he provided throughout my entire child support case. From our very first phone call, he gave me a sense of trust and confidence that never wavered. He walked me through every step of the process, explained everything clearly, and was always available when I had questions or concerns. During my hearing, he had my back every second. His preparation, professionalism, and dedication were evident, and I truly felt like he was fighting for me and my child’s best interest. I never felt alone in the process and that made all the difference. If you're looking for an attorney who will stand by you, guide you with honesty, and go above and beyond in representing you, this is the one you want. I highly recommend David R. Sachs to anyone who needs a strong, supportive, and reliable legal advocate.
    MsSoto
    Relieved by Protos Law Firm
    I just want to say, from the time I received my speeding ticket (89 in a 55 mph zone), I was worried about losing my driver's license. Although it was my first ticket of any kind in over 30-plus years of driving, I was extremely afraid of losing my CDL license. I reached out to Andrew Proto's Law Firm, and immediately I felt relieved! From the first phone conversation with his team, they quickly reassured me that everything would be alright. And I must say they were correct. I had to do absolutely nothing; Andrew and his team took care of everything from start to finish. They were able to get my situation resolved in a timely fashion without any points being assessed to my CDL driver's license. Much respect to how they were able to resolve the situation, which could have been catastrophic in my situation. Thank you! Keep up the great work!

    8 Point Ticket Reduced to Zero
    Mr. Sachs is one of the most professional, diligent, and knowledgeable traffic lawyers within Westchester County, NYC. This man got an 8-point ticket to zero. Can anyone beat that? I guess not!

    Keith Takes Your Case Personally
    Several years ago, I needed the services of an experienced attorney to handle a post-matrimonial matter. I performed my due diligence and after much research, my selection was clear, Keith M. Brown, Esq. I knew that I made the right choice when we had our initial meeting. It was quickly evident that Keith is a smart, hard-working, and very competent attorney, but he is also a real, compassionate and good human being with common sense. Keith took my case personally and dedicated the time to really listen and understand all of the facts. Throughout my three-year ordeal, Keith stayed committed and approached the entirety of this matter with the same focus and energy. Working together on my case for several years, I found Keith to be well-prepared, focused, professional, and ethical. He knows the law, he knows how to efficiently navigate the legal system, and he plays to win. With Keith’s collaborative approach, my opinion mattered and we worked together on strategy that made sense. I genuinely felt understood and well-represented to have the greatest probability of success. You cannot go wrong having Keith in your corner. I recommend Keith M. Brown, Esq. for your matrimonial and post-matrimonial legal needs.
    Spiro Sinanis
    Don't hesitate to call him.
    Seamless correspondence, extraordinarily attentive, and a wide range of knowledge is what sets Andrew Proto apart from others. He has helped us more than once, and both times took us through the steps of what happens in all circumstances. Time, thorough explanation, and sense of calm is exactly what we needed when we required an attorney. Everything handled in a timely manner, and we are so thankful. Don't hesitate to call him. Thank you, Andrew, once again.
    Randi Matalon
    Excellent matrimonial lawyer
    Keith Brown is an excellent, sharp, skilled, fair-minded, hard-working, and savvy matrimonial lawyer. He was easy to communicate with, strategically oriented, and handled my case with its many twists and turns, with clear-eyed analysis. He was highly detail-oriented and offered pragmatic advice. I would highly recommend him to all those who seek matrimonial law counsel in the NY metro region.
    Simon Spivack

    Case Dismissed Court Dismisses Alleged Violation of Conditional Discharge in Westchester County

    After a full hearing, a local Westchester County court dismissed a violation of conditional discharge that had been brought by the District Attorney’s Office. The client had previously pled to a Driving While Ability Impaired (DWAI) charge and was later rearrested for Driving While Intoxicated (DWI) in another state.

    Attorney review showed that the out-of-state case was ultimately resolved without a criminal conviction. Based on that outcome, the judge agreed that the client had not violated the original conditional discharge, resulting in the case being dismissed in full.

    Quick Legal Insights
    • Can custody arrangements be changed?
      Yes, custody arrangements can be modified if there is a significant change in circumstances that affects the child's best interests. A formal request to modify the custody order must be filed with the court, which will assess the proposed changes and decide if they benefit the child.
    • What is child custody?
      Child custody refers to the legal terms set by the court to decide who is responsible for the care and decision-making of a child after a divorce or separation. It can include physical custody, which is where the child lives, and legal custody, which involves decision-making rights about the child's welfare, education, and health.
    • Do children have a say in custody decisions?
      Children's preferences may be considered by the court, depending on their age and maturity level. While a child's opinion is taken into account, it is not the sole factor in deciding custody. The court prioritizes the child's best interests above all when making decisions.
    • What are parenting plans?
      Parenting plans are detailed agreements between parents outlining how they will raise their child post-separation. This includes scheduling, decision-making, and dispute resolution methods. A well-crafted plan helps ensure both parents are engaged in the child's life and can help minimize conflicts.
