Client Testimonials

Kind words from former clients.

Not only did Mr. Maze assist with my DUI case in 2021, I hired him AGAIN in Jan 2024 after being charged with a DV case that I did not commit. Fast forward 9 months and he fought for what was right and took it all the way to jury trial. With his prep, confidence and absolute lethal trial strategy, NOT GUILTY was the jury verdict. I felt heard, well informed and protected every step of the way. He is truly who you want in your corner!

Wonderful Attorney!
Mr. Maze helped me in 2013 by reducing the DUI that I received down to reckless driving. The DUI was the first and only ticket I have ever received, there was no accident, no-one was injured, and my BAC was 0.08. I did have an open bottle of alcohol in my car, which was wrong of me. While driving on the expressway I swerved while reaching for a bottle of water that had fallen out of the cup holder onto the floor of the passenger side of my car. I exited the expressway at the first exit I saw to clean up any spilled water. It seems someone that saw me swerve and called the police. When the officer asked me if I had been drinking I made the huge mistake of telling him I had had a drink earlier in the evening. I never should have answered that question in the affirmative. I am so thankful for Mr. Maze's help. I had actually met with a few attorneys and I had retained another attorney, then an acquaintance that is an attorney himself referred me to Mr. Maze. He told me what an amazing attorney he is. After meeting with him, I forfeited my retainer with the other attorney and hired Mr. Maze. I was impressed with his skill as an attorney but also his kindness and sincerity. Mr. Maze worked on my case for 6 months and made multiple court appearances. He showed dedication on my behalf as my attorney. Another thing that really impressed me about Mr. Maze is that he called me a couple months after everything was over and asked me how I was doing. That call demonstrated Mr. Maze's sincerity and compassion. I recently contacted him, five years after the case was over, with a question pertaining to that case and he remembered me and happily answered my question with patience. Mr. Maze is a skilled and caring attorney committed to helping his clients. If I ever need an attorney again it will be Mr. Maze. If you need an attorney Mr. Maze is the only attorney I would recommend.

One of the best
Mr Maze went way above to get a not guilty verdict . this was an accident case. Mr Maze for 16 months investigated, reviewed and sought out evidence and after a three to four hours deliberation came out with a not guilty verdict. I will recommend him to anyone.

The only lawyer to have by your side
I was a new graduate looking to begin my career and knew that this charge could have detrimental consequences to my future. Knowing the situation that I was in, I started to research lawyers and found that William stood out among the rest. He seemed to have the most determined personality and a drive to be the best. His reputation, certifications, memberships, and trial experience showed me that he really cared about what he did and was going to fight until the bitter end. His staff was very professional, informative, and helpful whenever I had questions or concerns. I always got quick responses and would be able to talk to Maze directly if I needed too. He was always prepared and knew exactly what our next move was going to be. I was walked through each part of my case and was never left in the dark. These factors let me know my case was always a priority. From the first day I met William he made me feel comfortable that my case was being handled by the right person and that he was going to do anything to work in my best interest. During this long case and many courtroom visits, William was able to keep my mind at ease, even when I felt I had no chance. I would even have a boost of confidence when he simply walked into the courtroom. This was because everyone knew who he was, and they knew it wasn't going to be easy. I am proud to say that I know William Maze and believe he will only get better as time goes forward. When the final day came, I finally heard the result of all his hard work. CASE DISMISSED!! "I recommend William as the only person you should have by your side during this time in life" "You gave me my life back, Thank You!"

Should You Submit to Field Sobriety Tests?

No. You always fail field sobriety tests, no matter how well you perform the tasks. Worse still — you always look guilty trying to perform FSTs.
