    "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.

    "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.

    "David gave me the feeling that I was going to be well protected in my trumped up, ridiculously racist criminal charges against me."
    After talking to a couple of other area lawyers, this firm seemed more aggressive. I met with David Sachs at my first meeting and he gave me the feeling that I was going to be well protected in my trumped up, ridiculously racist criminal charges against me. Money well spent. David was fantastic. He was able to have my case dismissed by filing legal papers with a court appearance with testimony (not a trial). Judge agreed with his legal opinion and dismissed my case. I can't thank him enough. Also, on one court date lawyer Andrew Proto from the firm appeared on my case which was fine, because I did hire the firm, but what was exceptional about it was that he knew my case just as well as David. In my view, this firm is top notch.

    "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!!!

    "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.
    - Former Client
    "He is very responsive and clearly knows what he is doing."
    Thank you for treating me as if I was a VIP. David did a great job getting my speeding charge dismissed. He is very responsive and clearly knows what he is doing.
    - Former Client
    "Andrew contacted me to discuss and followed through 100% on everything he said."
    Gave them all necessary info about my case using their website. Andrew contacted me to discuss and followed through 100% on everything he said. I did not have to personally appear in court. Andrew handled everything for me with the Traffic Court judge. Ticket I had was reduced to a small fine and no points on my license keeping my record clean and avoiding possible increased car insurance cost. Will recommend Andrew and his firm to any family members & friends in need of legal council.
