  1. DUI and DWI
    75%
    Every year the penalties for DUI are increased and enforcement of DUI laws gets more aggressive. Because of the political and technical nature of a DUI prosecution, successfully defending a DUI case takes specialized knowledge, training, and skill that most lawyers do not have. I've devoted a large portion of my practice to mastering the science, law, and courtroom skills necessary to fight for people accused of DUI and to helping people win their DUI case.

  2. Criminal defense
    25%
    Being charged with a crime can be a devastating blow and can have lasting effects on a person's life. I'm passionate about defending the rights of people charged with crimes and helping to provide peace of mind through the criminal justice process and the best outcome possible that helps preserve people's freedom, livelihood, and future.

The Barnes Law Firm was founded with its clients as the top priority.  That means we deliver every client a high quality, personalized, and aggressive representation, we are  available so that every client can speak with their attorney directly about their case and get the information and advice they need in a timely manner, and we provide those things at an affordable rate.  

 

Your peace of mind, experience, and case result drive everything we do.  That means we take on less cases per attorney than other firms so that we can spend the time necessary on your case and with you.  It also means we spend the time and money to develop the expertise required to make sure you get the best possilbe result in your case.  We think that representing East Tennesseeans is a great responsibilty and we take pride in delivering the highest quality representation.  We hope you will give us an opportunity to serve you or a loved one facing a criminal prosecution or hurt by someone else's negligence.

Great representation at an affordable rate.
I had a case come up that I was very nervous about because it was charges that were untrue and unfounded. I got in contact with several attorneys during my search period and Mr. John Barnes was the one I chose to go with. I chose him because he was attentive and very responsive. Not only did he respond to me the same day (even if he had been out of the office) on every occasion that we spoke, but he also seemed to genuinely care about my case. Since these were unfounded charges trying to be levied against me, I did not want to take a diversion or anything of that sort, I wanted to have this manner completely dismissed as it should have been. I had other attorneys consult me who seemed to be more interested in doing whatever was quickest or easiest. John Barnes was not one of those attorneys he knew that I wanted this manner dismissed without taking any kind of diversion or plea deal and that I needed this matter resolved asap, he worked diligently with me to achieve this goal. In the end all charges were dismissed within 2 weeks of the charges. I would highly recommend Mr. Barnes if anyone were needing legal representation.

Excellent Attorney
We felt comfortable speaking with Mr. Barnes about the case. In the office and in court, Mr. Barnes clearly explained all points of the situation. He never made us feel rushed or pressured into making a decision. His office was very good at contacting us prior to court appearances. Mr. Barnes responded quickly to phone calls if we had questions. Mr. Barnes and his staff are all very kind and respectful. We are very grateful for his representation and for the favorable outcome in our case. We highly recommend Mr. Barnes for any legal matters.

Amazing service and hospitality
My wife needed an attorney for a charge received while traveling to visit her sister in Maryville TN. We live in the Memphis TN area so it was hard finding an attorney out of town. We were very fortunate to find Barnes Law Firm. Attorney John Barnes assisted her with efficient results and the best outcome on her case we could ask for! We are very pleased and relieved with the service Attorney Barnes gave us. I would recommend Barnes Law Firm to anyone seeking assistance in a criminal law situation. Thank you!

Great Results!
The Barnes Law Firm, specifically John, Lauren and Ed are very professional and, although the wheels of justice (self [justice] initiated in my case) move slowly, the firm guided me through the foreign (to me) process, kept me abreast of any changes of circumstances and comforted myself and family through a successful process of dismissal and, ultimately, expungement. Thank you to the entire staff!

Absolutely Professional, Effective Lawyers & Firm
John, Lauren & Ed are absolute professionals. There is not another firm that I would recommend more than Barnes Law. I called Barnes Law and immediately received a phone call back from Lauren. Within just a very short time I received a call from John to discuss my legal issue. John and his team answered ALL my questions, emails, concerns and phone calls instantly and with precise information regarding my case. They worked tirelessly on my case and I got the best resolution possible. Additionally, Barnes Law worked with me on paying for their services so that I could get the immediate attention that my legal case needed. Most importantly John, Lauren and Ed helped me to restore my family and helped me to get back to them quickly. There is nothing that can compare to this for me. I would highly recommend, if you find yourself in any legal situation, to contact Barnes Law as quickly as possible. Regardless of the industry or service, I have never seen any collective group of individuals care so much about what was going on with me as an individual.

Barnes Law Firm
I was arrested for a crime which I did not commit. I was facing jail time and some very expensive consequences if I had been convicted. Thankfully, I reached out to the Barnes Law Firm. Due to their professionalism and competence, all charges were dropped. They're very good people to know if you're in legal trouble.

Cant say enough good things about John. He was by my side from the very start and always kept me informed on what was happening with my case. He had to educate me about a lot of things but always did so with patience and respect. He and Lauren worked really hard to help me through the most devastating and scary thing that I have ever faced professionally. Grateful for all they did!

This office is the best decision that i could have made
It's hard to describe my experience with mere simple words. I hired John Barnes and it was the smartest decision I could have possibly made. This sort of thing is a horrible ordeal to go thru ..full of uncertainty and fear but I can honestly say that I wouldn't have the peace of mind I do now if it weren't for John. This gentleman seriously cares and listens to every detail you give him and takes all of this into consideration and thoroughly analyzes and reviews every aspect to represent you to the best of his ability. Yes i probably sound like a commercial but this is real...this is my real life and this man helped me and cared and did everything he could. My outcome was very very good. If you need to hire an attorney your search is over if you want a smart, fair, hardworking individual who knows exactly what he is doing. I also want to add that he was always available to answer questions anytime about anything and help put your mind at ease. Finally...his assistant Lauren is the most amazing lady. I sent Lauren so many emails about various things and questions and concerns and she always listened..answered and encouraged...I cant explain how much she helped me on a practically daily basis. Yes this has been a lengthy review but I barely scratched the surface because while I still have alot to deal with in the upcoming year or so I wouldn't have gotten results like i did without this team. Thank you guys from my heart and my family.

Best lawyer to call if you have legal issues
First off, I had a case that was virtually unwinnable. I did something really stupid and out of character while under the influence of drugs. I shoplifted and was caught red handed. It was a nightmare, and being that I was caught on camera, the best thing I could do was plead guilty, and accept my punishment. Mr. Barnes somehow convinced the D.A. to get me a lesser charge of attempted shoplifting, which is a much lesser penalty and not as serious as actual shoplifting. I still don’t know how he did it, but I gladly accepted it. Not only is he a great lawyer, but very understanding and a really nice person. I’ve since learned my lesson and have straightened myself out. But if I was ever in trouble again, he would be my first call. I can never thank him enough for what he did for me.

Excellent Attorney for DUI
I was pulled over in November of 2015 for DUI. The officer asked me to get out of the vehicle and perform some tests. I did a few of them but was extremely nervous as I have an anxiety/panic disorder. I decided to refuse the rest of the tests which automatically sent me to jail with an implied consent charge. I also had some prescription medication on me and some handguns which I have a permit for. I was in dire need of a lawyer and had no idea of who to hire. I started researching and came across John Barnes. I decided to hire him and I am forever grateful that I did. I had never been in trouble before, so I didn't know what to expect. My case took a long time to settle, but I am pleased to say that my case was dismissed and everything was expunged from my record. I was so worried in the beginning about every little detail. The thing is, that John knows the laws and knows them well. He will know things a regular person as myself would never dream of. He fought for me and I would highly recommend him should anyone need an attorney. Again, I'm grateful that I did!

DUI case
Mr. Barnes is an amazing attorney. He went above and beyond to ensure that I was given a fair trial. He is very knowledgeable and uses it very well when defending his clients. I was not sure what the outcome would be or even if he would be able to help. But after sitting down with him and going over the details I knew Mr. Barnes was a man with integrity and was the right fit for me. He looks at things from every possible aspect and answered all questions with honesty and even when approached with a statistic what if question he was very honest. He listens and discusses with you about what could happen and what he is going to do there is no second guessing anything with him. He made my family feel comfortable and secure with what to expect and how important each step was that we were taking and left the choice up to me and did not force me to make any choice I did not feel was right. When looking for an attorney this is the man you want on your side he is professional, knowledgeable, honest, and does not question or look at you as a criminal in any way he treats you like a person and respects you all the way. I would recommend no one but him to represent anyone in trouble.

Case Dismissed
When I retained Attorney Barnes to represent me in my DUI 1st Offense case, I was confident, at the onset, of his knowledge and ability to successfully fight my case. While I had moments of doubts over the course of several months, due to the fact that he was honest about the potential outcomes, those doubts quickly dissipated during my preliminary hearing! I was rendered speechless as I watched and listened to him professionally, fiercely, and successfully disprove the legality of my initial dui stop. The Judge ruled in my favor and dismissed the case! The best legal defense ever and I can’t recommend him enough. Amazing! Thank you Attorney Barnes.

Career Saving Decision
I was charged with 3rd offense DUI and was very stressed to say the least. But after my initial consultation I was at ease. So, I knew that John was the right lawyer for my case. He asked me what my expectations were and he not only met them but he greatly exceeded them. John represented me in a way that my charge was reduced to 1st offense. John thank you so much for your expertise and professionalism you showed me in regards to my case. Also, thank you Lauren for your support. Best Regards, Career Saved!!

Relationship: Worked for lawyer
"John has many skills that make him an exceptional advocate. John truly takes the phrase “client-centered representation” to heart. He insures that every client feels as if they are his primary concern by listening to their concerns and thinking critically to resolve their legal issues through highly-skilled advocacy. John has incredible success at reaching a successful resolution in each of his cases by explaining his clients' stories in the most beneficial way possible based on the applicable law. As one of John’s associates, I can truly say that I am honored to have John as a boss and a mentor. John has provided me with the opportunity to witness firsthand how he is able to relieve his clients of their worst nightmare by aggressively advocating on their behalves. Whether you are facing criminal or DUI charges against you, or you are the victim of someone else’s negligence or intentional act seeking compensation, you will be beyond grateful to have Barnes Law fighting for you."

"One of the best trained DUI defense lawyers I have ever run across. Sure, there are many lawyers who will lure you in with discount pricing. DUI is not one of those areas where you should be looking for the cheapest. The consequences of a loss can be monumental"
DUI and DWI Attorney | Jun 08
Relationship: Worked together on matter
"I have known and worked with John for several years. He is probably the best example I can think of in saying that a lawyer doesn't necessarily have to have been in practice for 30 years in order to have the level of knowledge and the capabilities which would be expected from a lawyer with 30 years experience. He is extremely knowledgeable of the law, and highly adept in working the law to the benefit of his clients. John is respectful of his clients, sensitive to their desires and needs, and also realistic with then regarding their expectations. Most importantly, his personal integrity and professional ethics are unimpeachable. John is a great lawyer now, and he has many years ahead to become even better."

"There are two ways to practice DUI defense for an attorney. They can take as many cases as they can and just plead guilty or they can put in the time to defend someone the right way.
