A friend of mine was represented by this attorney and he did the best that he could with a complex case. This was A+++ and appreciated 100%. He was professional and kept the family informed and updated as to what would be next which was also very helpful. Thank you so much Mr. Quinnan-I would prefer anyone to you anytime!

Do not retain Mr.Quinnan if you are in need of an actual advocate. He is sadly a cog in the broken machine. When things get tough he won’t be there for you. He is a man’s man in every sense of the word and I’m sorry that I made the mistake in trusting my life to him and his partner Peter Kuykendall. In my most crucial moment they deserted me and blamed it on the “fine print.” I guess speaking the truth was simply too much for these boys to handle. not a huge surprise there. Buyer beware.

Mr Quinnan was very thorough in representing me his brilliance in hiring the investigator needed in my case was great. I went from serious felonies to misdemeanors. I hope I never have use him again but if ever in trouble I'm gonna want his representation again.

Let me tell you about Gabriel! He is the Sonoma County Johnny Cochran and will work to get you a fair trial. He is the DA slayer and knows exactly how to ensure freedom. I was being tried in a case where me and my co-defendants were being charged with a robbery and some other erroneous charges. Gabriel, accompanied by three other defense attorneys, tore holes in the prosecution. Enabling the jury to see the real truth and exposing a dirty, prejudice, over zealous, unfair prosecutor. He is so poise and knows how to take a case piece by piece and destroy the prosecution. He is a genuine attorney that really cares about his clients and their personal well being. There is no other attorney in that county that will fight harder than Gabriel. TRUST ME! This was a huge case in the county and we are now free. FREE! FREE! FREE! He will do over and beyond what you will ever expect!

Mr. Qunninan represented me and I am very with the outcome of everything. It was a scary experience going to court but he assured me and things turned out great. I wouldn't want anyone else representing me, now that it's all over I am relieved to have had someone really fighting for me.

Gabe Quinnan is an absolutely incredible Attorney. Gabe represented me on a Court Matter that has was incredibly complex and multi-layered. This was a matter that could have gone to trial. Thanks to Gabe's incredible representation, the matter was Dismissed at the Preliminary hearing and we never had to go all the way to trial. Gabe was available and would always answer my calls in a timely manner. He thoroughly went over every step of the case. He always showed up to Court early to make sure we had time to talk before walking in. And, if I ever needed to work with an attorney again, Gabe Quinnan would be the only attorney I would speak with.

Mr. Quinnan is definitely one of the best lawyers in all of Sonoma County. With a genial smile, his assiduous nature, and a remarkable talent as a lawyer, he was able to convince the D.A. to not file any (multiple felonies) charges against myself. Mr. Quinnan is attentive, cares about your need, and will do his best to achieve the best possible outcome. If you are facing legal issues, then it is your best call to go see him. Thank you Mr. Quinnan for your support, help, and for saving my life!

Gabriel is a very imformative Attorney, my husband was recently incarcerated and he was able to get my husband a good deal compared to the time he was originally facing. He not only kept my husband informed of what he was doing and answering his questions on a timely manner. Gabriel also kept my father in law and I informed on everything that was also happening and was there for us any time of day to answer our questions. Gabriel is a very down to earth and very easy to talk to. Gabriel is very knowledgeable of his Practice, and I would highly recommend him to anybody looking for a good, friendly and knowledgeable attorney .

Best Lawyer out there, I was in a case where I had a Public Defender wanting me to accept the DA's plea bargain even though I was innocent. Public Defender basically stated that there isn't really a chance of me winning this case at all and most likely I would be found guilty. Soon after I hired Mr. Quinnan, and he was able to get my case dismissed without even going to trial, one of the best lawyers out there and I would highly recommend him because, he basically saved my life.

Mr. Quinnan is always professional, courteous and pleasant. It is rare to find an attorney who takes their time to listen to what the client's needs are. Most attorneys just rush you through and then bill you for time you know they did not work for you, instead you will find integrity and honesty with Mr. Quinnan. I cannot thank him enough for his attention to detail and being a champion for civil rights!

I used Gabriel to represent my son who got into legal trouble. He was easy to get in touch with. I felt like he went out of the way to talk me through a tough time. He also provided excellent representation of my son in court. The guy is a rock star! I highly recommend him.
