Awesome Team!

Oscar and the entire team are awesome! I was arrested with 2 felony charges. Having never been arrested, and not knowing how to move forward, Oscar and his team assured me from our first meeting that they would achieve the best results for my situation, and they did. My case will be completely dismis...sed. I do not know what my family and I would have done without their expertise. The entire team is caring, professional and confident, and I recommend consulting with them before contacting any other law firm!

Oscar review

Oscar was very professional and did not beat around the bush about anything he was completely honest about everything. He was an absolute blessing to have as a lawyer he made me feel like my case was the most important one in the office 10 out of 10 recommend if you have to deal with a dui type case

DUI Case

Following a bad decision and finding myself in a difficult and overwhelmingly stressful situation facing a DUI charge, I was fortunate to find an exceptional attorney, Oscar Butler to stand by my side. He immediately put me at ease with his knowledge and expertise in dui cases. His communication was ...outstanding. He kept me informed about court dates and suggested classes I should attend to assist my case. He made me feel at ease on court days and displayed a great demeanor. He showed he really understood the court/legal process and always worked towards the best outcome for me. Thanks to his hard work and expertise, my case concluded with a better than expected outcome being dismissed with community service requirements. I am truly thankful for having Oscar and his team on my side. If you find yourself in an unfortunate circumstance, do yourself a favor and hire Oscar Butler with Barnes and Fersteen group and you will not be disappointed. You will be able to rest knowing they will be on your side working your case in your favor. Thank you again, Oscar for your dedication, exceptional support and expertise. I am forever grateful.

Great guy

We retained the Barnes & Fersten law firm for help with an unfortunate situation. Our initial meeting with Oscar and Brandon was extremely insightful as they provided valuable advice, warnings, and a detailed explanation of our legal options. As newcomers to the criminal justice system, their expert...ise was truly refreshing. Following our consultation, we discovered that no charges had been filed at the courthouse. They even returned our retainer and declined any payment for their services. Despite this, charges eventually did appear. Oscar's strong professional relationships and understanding of the legal system allowed us to navigate through this situation successfully. He kept us informed, gave us guidance, and involved us in the process as necessary. He focused on his area of expertise and referred us to a skilled colleague for custody matters. The office manager, Lauren, was exceptional as well. She established an efficient system for information exchange and ensured that all communication was promptly relayed to Oscar. Thanks to the hard work and dedication of the entire team at Barnes & Fersten, we were able to rectify a difficult situation. We are grateful for their assistance.

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."
