Attorney Andrew O'Donnell

Andrew O'Donnell has been an integral part of Barnes & Fersten and quickly received extensive experience of defending clients at the highest level. Andrew has dedicated his entire career since graduating from the University of Memphis Law School in 2022 to defending clients charged with DUI and the most serious felonies.

Andrew joined Barnes & Fersten in 2024, following two years at the 9th District’s Public Defender’s Office where Andrew successfully represented hundreds of clients in DUI, drug, misdemeanor and felony cases. Andrew joined our office because he wanted to provide a higher level of representation to his clients with more personal communication and more time to dedicate to each individual case to ensure the best results for his clients.

Andrew is a graduate of the Tennessee College of Criminal Defense and a member of the National College of DUI defense (NCDD).

Andrew follows the values of Barnes & Fersten to the core by providing the highest level of customer service, and providing the same dedication and desire to win to every client from DUI cases to felony drugs and violent crimes. Andrew’s desire to learn through national conferences and trainings by the best attorneys in the nation prove his desire to be the best criminal defense attorney and DUI attorney in East Tennessee. That is why he wanted to work at Barnes & Fersten where the team is dedicated to being the best and providing the best service. Andrew provides such service every day to all the clients cases he touches. Andrew has gotten countless favorable results for our clients including DUI’s and felony drug and violent crime cases dismissed and reduced significantly.

Originally moved from Ft. Lauderdale Florida to Tennessee with his family in 2005. Andrew graduated from Bearden High and The University of Tennessee at Knoxville before heading to Memphis for law school. 

During Law School, an internship following a criminal defense attorney steered his attention towards the justice system. He spent his second and third years in school shifting from employment and labor law to criminal defense. 

Before joining Barnes and Fersten he spent two years as an assistant public defender in Roane and Loudon. He enjoys advocating for his clients and helping them achieve the best outcome possible. 

Andrew enjoys ice hockey and is a lifetime Boston Bruins fan.

What Our Customers Say

Brandon was amazing throughout the entire process. I was losing faith and wanted to give up but Brandon kept encouraging me and fought really hard on my behalf, his hard work and dedication to my case got my DUI 1st offense charge downgraded to Reckless driving. I will forever be thankful for what he did for me. Thanks Brandon!!
Barnes & Fersten are some phenomenal people! Brandon was my attorney and he did amazing work! He was very professional, kind, and knowledgeable in his field! He came in and did everything he said he would and I walked out with best case scenario for my case! I would recommend Brandon for anyone that needs attorney services. Brandon was very communicative with me through everything as I live 3 hours away from him and the court we went too. I was never kept in the dark and I was 100% satisfied with everything he did for me. Thank you Brandon
All these previous 5 star reviews are truthful. I retained this law firm for a very serious potential felony juvenile case. Brandon represented our child, took the time to answer any and all questions we had, and provide us legal advice that went above and beyond his retainer. He truly wanted what was best for our child and to represent our child to the best of his ability. Lauren, who is the office manager is very kind, responsive, and takes her time to listen and answer any questions or concerns. Both Brandon and Lauren working together made us feel at ease through the stressful process. They will truly be missed as I feel they are an extension of our family. I recommend Brandon to represent your child in any juvenile criminal case. Call their office and speak to Lauren, you will quickly feel like a valued potential client. Our case was resolved with a very positive outcome for our child.
