Awesome representation!

I had an excellent experience working with Oscar. From the very beginning, He was professional, knowledgeable, and responsive, and he took the time to clearly explain my options and what to expect. He was always straightforward with me. I always felt informed and confident that my case was being hand...led carefully and strategically. His attention to detail and commitment to my situation made a stressful process much easier. I would highly recommend Oscar to anyone looking for outstanding representation.

Outstanding Attorney

⭐️⭐️⭐️⭐️⭐️ Outstanding Attorney — Truly Cares About His Clients I cannot thank Oscar enough for everything he did to help my daughter through a really difficult and frightening situation. From the very first meeting, he treated her with compassion and respect, taking the time to truly listen and ...explain every step of the process so we both understood what was happening. Oscar fought hard for her and never gave up, even when things seemed impossible. His professionalism, dedication, and calm confidence made a world of difference for our family. Because of his hard work, my daughter was able to get a second chance and move forward with her life. If you’re looking for an attorney who genuinely cares and goes above and beyond for his clients, I highly recommend Oscar. He’s not just a great lawyer—he’s a good person who makes a real difference.

The best lawyer

On behalf of myself, i would like to thank Mr Oscar A. Butler for solving a big messy charges (DUI First Offense, Implied Consent, Speeding) to dismissed. Mr Oscar solved it in less than a minute at the court in the first court date. he has been always communicating and answering my questio...ns, and even when he is busy with other clients, he will find the way to call back. Also, It has been a pleasure working with Ms Lauren Bledsoe-Williams. she was really an excellent assistant. She was very helpful with all the paperwork I needed. Thanks Mr oscar again and all your Brandon D. Fersten.

Domestic Assault Case - Dismissed

I can’t thank Oscar Butler enough for the incredible job he did with my case. From the moment I reached out to Barnes & Fersten, Oscar was professional, supportive, and truly dedicated to getting the best outcome for me. My domestic assault case was dismissed with no conditions or costs, the remote b...reath device was removed, and my case is being expunged—a huge relief! What stood out to me was how Oscar and the firm made a stressful experience so much more manageable. He took the time to explain everything clearly and was always there to answer my questions. His work made a huge difference in my life. If you’re looking for a skilled, caring attorney who gets results, I highly recommend Oscar Butler at Barnes & Fersten. Thank you again for everything!

Fantastic Representation

My experience with Barnes & Fersten was nothing short of exceptional. The entire staff was extremely competent and professional, from beginning to end. Tim, the intake coordinator, was my initial contact and put me at ease during the process and was also of great help whenever I needed to coordinat...e with or contact the team. Lauren kept me informed of everything going on with my case as things moved forward, and her professionalism and patience were very much appreciated. When I first met with John and Brandon they immediately made me feel like my case was being taken seriously and that they had every intent to fight to make sure that I received the best possible representation. I never felt like I wasn’t a priority or that my case was just a number. They cared about my case just as much as I did. Lastly, I could not have asked for a better lawyer than Oscar Butler, who represented me in court. Oscar listened to my questions and concerns patiently, and took the time to answer them with care and intelligence. And Oscar really fought for my case, and got me a better result than I ever expected. I cannot recommend the Barnes & Fersten highly enough, they are not only consummate professionals, but also great people. Choosing legal representation can be tough, but if you go with Barnes & Fersten you are in the best possible hands.

Relationship: Worked together on matter

"Oscar has a wealth of experience from clerking for a federal judge to working 4 years as a Knox County prosecutor to now working in private practice as a criminal defense and DUI lawyer. Oscar's experiences put him in the best position to get the best possible results for his clients. He understands what prosecutors are concerned about when they prosecute a new criminal case and uses that knowledge to put the prosecutor at ease when making a favorable offer for his clients. Oscar takes the additional time to learn about each of his clients to ensure their desires in seeking representation are not just met but surpassed. I know anyone who hires Oscar as their attorney will feel they made the right choice in hiring him at the conclusion of their case."
