Was a great help during a difficult time for my daughter
My daughter was in trouble after dating a man that was really bad person. He was a crook trying to make money from stealing and ripping people off instead of honest and hard working. He took advantage of her naïveté and used her for her car, her credit status and her money ie: writing bad checks all over the place from her account. Because her name was on everything not his she was held responsible as there was no connection paperwork wise to him. He left her in a bad way with all these debtors. Luke Rioux was the best person to get them to understand that she was taken advantage of and to get the amounts owed to them lowered and her restitution lowered or she would have been in more trouble as she might have even had to go to jail for what that guy did to her. We are thankful to Luke for helping her tremendously!

Great Lawyer for Moving Violations

Luke is undoubtably at the top of his game. The reason is because while he is extremely attentive and one of the utmost professional, kind, well-rounded and knowledgeable attorneys I could've chosen for my situation. I am fully confident in his ability to listen to what is needed as well as successfully attain goals that other attorneys simply do not come close to reaching. My experience with Luke was a pleasure and I would recommend him as an attorney to my closest friends and family as well as any stranger on the street . Because simply put when the job needs to be done Luke Rioux is your guy. Do not be mistaken! Luke is A+

Very Good Attorney
Luke represented me and did an excellent job. He had my traffic violation reduced dramatically. I would recommend him to anyone in need of Consul in Maine. He negotiated a very good settlement with the DA and charges were reduced. A very good attorney and a good person. T.S. T.S.

Complacency will COST YOU !
The firm Esq. Rioux was with was in the news on a high profile criminal case is why I called him. Defending the little guy on charges from an overzealous police department. I support my Police but have witnessed piled up charges levied to make a couple stick ! NOT RIGHT ! We don't have a perfect Justice system BUT we do have the BEST !! I was tired of paying my present Attorney on a never ending saga of the X filing another "Protection From Abuse" PFA complaint on me whenever she broke nail ! He had no intentions of seeking to dispose of it. I had drilled him to do so. Good for 5K a year for making a few phone calls. All charges had always been dropped. No merit to the complaints. Now the DA wasn't going to drop any more. PLEAD GUILTY ! NO I don't think so. Trial by Jury 10K up front for STARTERS ! Again I said " I don't think so" ! I had paid him 12K to date. He didn't think I would jump. His partner my divorce Esq and Corp. Esq. I retained "LUKE RIOUX" after a sit down and I heard the word BIZARRE used I knew I had found an Attorney thinking like me ! WE WON ! Short and sweet. WE WON ! Now Luke is moving to dispose of the matter once and for all ! No Patty Caking or Milking the Cow ! Isn't that what YOU are looking for in an Attorney ? There's nothing wrong with paying good money for good results ! Luke Rioux was very reasonable with his fees with excellent results. Job well done ESQ RIOUX. Thank you.

No Jail Time
Luke did an excellent job handling my case. With my somewhat extensive driving history, he accomplished more than I thought possible with the prosecutor and most important of all kept me out of jail. He was very respectful and informative. In addition, when I was interviewing attorneys he was actually recommended by someone I interviewed. I would recommend his services to anyone having a run in with the law. Thank You

An outstanding job
Luke Rioux with Fairfield & Associates is more than a fair attorney; hi did an outstanding job! Being out of state person, I got a ticket for a double moving violation in the state of Maine. I found Luke with Fairfield & Associates online. Luke explained the process and options I had and made no guaranties. Wow you don’t want to get a traffic violation in the state of Maine! To my surprise Luke got me off both violations. I did not pay hefty fines, no points, no violations, only filing costs, a fraction of what I would be out otherwise. Luke delivered by saving me grievance, time, and money. All with one phone call and a couple of follow-up emails, service worth every penny in my books.

excellent job. very knowledgeable
Luke did an awesome job with my case! It was my first OUI and it was a completacted situation but he handeled it beautifully. He got the prosecutor to drop the charge. I cannot thank him enough for the work he did and I will forever appreciate it. I can carry on with my career now not having to worry about an OUI on my recored. I would highly recommend him for any case!

Great OUI Lawyer
Luke was a lawyer who reviewed my OUI case and ended up working out a plea for me. He excels at his job and I would recommend him to anyone who finds themselves charged with any type of dui.

Excellent OUI Defense
I hired Attorney Luke Rioux to represent me after I was arrested for a second OUI. Because of the seriousness of the potential consequences, I did a lot of research on local attorneys in the Portland Maine area, and compared the "free initial consultations" of probably 10 different lawyers. In the end, I chose Luke because (a) he offered his counsel at a very reasonable price, and (b) he came across as genuinely concerned about trying to help me. Luke did an excellent job the entire time and we communicated openly and regularly. In the end, we got the charge reduced to a second "First Offense OUI", which was a result that I was very happy with. I could not recommend Luke Rioux more highly.

Luke Rioux - a Trustworthy lawyer
Luke Rioux was of a great help and my case was resolved just the way I wanted it. Thank you so much !

Highly Recommended
Mr. Rioux is a standout amongst his peers! He is completely professional, honest and I felt like he actually cared about my best interests. He did not attempt to bully me into paying for services that I did not need and his rates are completely fair. If you find yourself in need of an attorney, don't be fooled by the high-priced & flashy attorneys out there. I originally opted for one of those and ended up paying 15K for an "expert" that actually ended up hurting me in court. Mr. Rioux never once tried to get more money out of me and he ended up helping me a whole lot in court. You would do well to hire Mr. Rioux!!

Not worth the money
Luke did absolutely nothing for my case. He seemed distracted and uncaring. I should have saved the thousands of dollars I paid him and just represented myself. The outcome would have been the same.
Response from Luke Rioux October 1, 2015
I am very sorry to see these comments and I wish I could have done more for this anonymous client. I try to do my best in every case but, given the mandatory minimum penalties that legislatures have set for some case types, it can sometimes be very hard to change the ultimate outcome. It is my job to research and raise legal and constitutional defenses and to advise my client accordingly. The one thing I can't do is change the facts or circumstances that lead to the charges and that is what often drives the court's decision. I wish things had ended differently for this unknown client. Unfortunately, they didn't. Hiring a lawyer is always a difficult decision and no results are ever guaranteed. All I can do is give my clients a better chance at a favorable outcome; sometimes, no amount of hope and effort can make that a reality. In those cases, none of us walk away happy, all we can do is learn from the experience.
