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.

Proactive and Professional

Oscar was very professional and went out of his way to help my son with his legal issues. I would definitely recommend him to anyone who has legal issues.

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!

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!

Criminal defense lawyer | Aug 28

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."

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
