I was born in Canada, went to law school in Montreal and got married to a beautiful American! We now have two children, and we live in upstate New York. I was lucky enough to have the opportunity to work as a sous-chef, a logger and a carpenter in my younger years. I have dedicated the last 15 years of my life to law. I now have a Master's Degree in Law and i regularly practice in New York and in Quebec. I have been hadnling criminal cases for almost ten years now and i have been involved in Immigration Law for about 5 years. I routinely represent Canadian clients who face criminal charges in the United States, whether in New York  or federal courts. I've also handled hundreds of TNs, L-1a and L1-b visas.

When i'm not practicing law, and after the kids are in bed, i like to create metal scultptures, fix broken engines and listen to and play music.

Great Lawyer and Person
David was a great help. He was super friendly and easy to talk to. He answered all my questions, and he explained everything that I did not understand. He helped me win my case for trespassing. I would highly recommend him as your lawyer with anything. Talk to him ask him questions and he will guide you to the right path. He had faith in me the whole process.

Hired For Legal Trouble
Mr. Gervais was the best attorney I could've asked for. When helping me with my legal troubles he went above and beyond with every hiccup that arose for me. He went with me to the DMV directly to help solve my issues.

Highly recommend!
This was my first time having a criminal lawyer. David was friendly, transparent, informative and most importantly he answered all my questions to ease my mind. He always let me know that he was available if I needed reassurance and cared. He was extremely prepared, professional, and well worth it. I thank you from the bottom of my heart and I'm very happy with the outcome of my case. I highly recommend David to anyone who is looking for an attorney to represent them, you will not be disappointed.

Fully Satisfied - Immigration Case
My husband and I hired David for an immigration case to get residency for my husband. He provided a list of everything that would be and was requested for the process. Once it was all organized the process went smoothly. His secretary did a perfect job with the organization of the petitions that were filed. From the date of file it only took 3 1/2 months! We are very satisfied with David's work and highly recommend him for his knowledge about this process, his hard work and dedication.

Thankful for the services of David Gervais
I went to help from David Gervais for a speed ticket in a school zone I felt I did not deserve. David was professional and personable. He helped me obtain my goal of point reduction on my licenses. I would highly recommend his services to anyone. I am thankful and impressed with his knowledge.

Understanding, Knowledgeable, and Effective
I can't thank David Gervais enough for his incredible support. Not only did he demonstrate remarkable legal expertise at all court hearings, but he also has exceptional interpersonal skills. He returned my call for help and scheduled a consultation within 24 hours; meanwhile, other firms never called back. His understanding of mental health issues also sets him apart from other attorneys. He treated my case with utmost compassion and empathy, recognizing the complexities of my situation and reassuring me along the way. He proved that he fights for his clients with integrity by getting my case resolved promptly. Thanks to David's diligence and extensive legal knowledge, he successfully reduced my charges, offering me peace of mind that I will forever be grateful for. David is a remarkable lawyer, and I highly recommend him to anyone seeking understanding, dependable, and effective legal representation.

The Last Defense !!!! Amazing!
If you’re a resident of Clinton county , you need to have this man’s name and number on your phone!!!! … If you’re not in law enforcement , or have connections and find yourself in a jam, you want this lawyer !!! Unfortunately , I have had the need for many criminal defense lawyers in my life; for many different reasons , both (state and federal) ; David is one of the best!!!! I mean it , he listens, without judgement , and he delivers success!!!! It’s not about the money… I felt like I had to force him to my money for a job well done!! If you judge the end results, to the cost ; he is priceless ….. If you have any wisdom how the world turns, for the everyday people of this community … I just can’t recommend David enough . He is best !!! Sincerely , Paul Masterjoseph and Dr.Maurer M.D.

Very Professional and Super Personable
Mr. Gervais is very professional and went over in detail the ins and outs of my case, what I should expect, and even future prospects upon conclusion. Mr. Gervais is very thorough, and you can tell he cares about his work and how his clients will be affected. I would recommend him to anyone.

Professional, patient and sympathetic
With David’s help, my case was finally dismissed. It took almost 9 months and many procedures, but David has been consistently patient, kind and professional during the process. He is the kind of lawyer that you can trust and depend on. I feel great relief every time having talked to him during the process. I highly recommend him.

Perfect example of what personal attention and above thorough representation should be.
I could not have imagined and or wanted a better experience and representation than this situation. Dave was very attentive to the situation and thorough would be a gross understatement for sure. Even though last minute changes actually caused us to receive a better appearance outcome, Dave already had a plan in place that would have secured a positive outcome that anyone and everyone would want and or expect. Besides all of this, he also drafted me a personal letter explaining the situation to future employment prospects for me so I could secure a 100 unbiased employment opportunity. Dave will work for and with clients not just a person hired but above and beyond that on a personal level which in my opinion makes him and his office a shining example of what law should represent. I would recommend 110 % Sincerely, Travis Marchiano

David did an excellent job from the very beginning to the very end of a year long journey to get my citizenship. Even though it was a long while to get to where I am today as that is the process to get ur citizenship. David did everything he could to make sure my case was in order and that it went smoothly. I had many questions through out the process he answered them all efficiently and throughly. My case was a unique. Something I I have stressed a lot about. He handled it all. I truly can not say enough good things about him. The best lawyer around. Thank you again for helping me accomplish this. Now to life my life to the fullest and travel to see the world!

David Gervais is a true professional! We were referred to him by another Attorney because we live far from where the incident took place, and we could not be happier with the outcome and the way in which David carried himself both, personally and professionally! A true gentleman with extensive knowledge of the law!
