Seth Holliday

As a partner at the McMahan Law Firm, LLC, D. Seth Holliday litigates disability, health and life insurance claims on behalf of individuals who have been wrongfully denied their benefits. He is also dedicated to representing the seriously injured in personal injury litigation.

Regarding private insurance benefits, Mr. Holliday has sued such insurance companies as Unum, Hartford, Prudential, Standard, Guardian/Berkshire, Cigna, MetLife, Aetna, Liberty Mutual, Mass-Mutual, and others that have denied individuals their private disability insurance (called “long-term disability” or “LTD”), life insurance or health insurance claims. His track record here is superb, and he obtains excellent results for his clients. Mr. Holliday is one of only a handful of attorneys across the United States who practices heavily in these areas. He has represented well over two thousand claimants at Social Security hearings and has a very high success rate.

Attorney Holliday is a 1996 graduate of Washington University School of Law and he initially practiced in Chicago, Illinois. There, in the personal injury context, he had a principal role in obtaining three awards which were confirmed by the local jury verdict reporter as being the highest on record in the State of Illinois in their respective category.

Attorney Holliday has been a leader in prominent organizations. He is a former member of the Board of Governors of the Tennessee Association for Justice, past-chair of the Disability Law Section of the American Association for Justice, past-chair of the TBA's Disability Law Section of the Tennessee Bar Association, and past-president of the Chattanooga Trial Lawyers Association. These are all associations of lawyers who advocate on behalf of injured or disabled individuals. Mr. Holliday has lectured regularly on disability issues to other attorneys and has also taught trial advocacy at the DePaul University College of Law in Chicago and business law at Chattanooga State Technical Community College in Tennessee.

Additionally, Mr. Holliday provides free legal services to a variety of charitable organizations in the Chattanooga area, including the Chattanooga Community Kitchen and Legal Aid of East Tennessee. He is a two-time past recipient of the Pro Bono Excellence Award. Mr. Holliday is a former member of the board of directors for Hospice of Chattanooga, having served as chairman of its governance committee and as a member of its executive and finance committees.

    McMahan Law Firm did a great job for me! They always took my calls (or returned my calls) and addressed my concerns and questions. I'd highly recommend them! Thanks Seth & Julie!
  • Knowledgeable & Well Prepared

    I am so glad I found this firm in the computer web search. Mr. Seth Holliday is knowledgeable well prepared . He went to my adjudication well prepared and countered every remark the social security rep said. I had been fighting the social security system since 2010 getting denied time after time....

    Knowing my case is not a large "money maker"... I didn't expect much, but, Mr. Holliday has gone above and beyond what i expected when starting my case. Julie was very attentive during the "waiting" periods. I only called a handful of times but she was extremely thorough and answered all question...

    Mr. Holiday and his staff are the best. I was updated on my case and they went above and beyond. Anytime I needed information, they responded quickly.
  • Thank You!!

    When I began my search for someone to represent me, I knew that it would be one of the most important decisions that I would ever make. Since mine was a disability case, the person I chose would have a profound impact not only on my life at this point in time, but also on options that I would hav...
  • Their dedication, knowledge, and professionalism have brought my claims to successful resolution

    Seth Holliday has represented me in both my Social Security and long-term disability insurance claims. He most recently represented me at my Social Security appeal hearing. In every instance his dedication, knowledge, and professionalism have brought my claims to successful resolution.


Seth has always been compelled to excel, whether it meant earning his Eagle Scout as a teenager, participating in theater, debate and varsity football in high school, his Rhodes Scholar candidacy in college, or opening his own law firm. He also perseveres in situations others might shy away from, whether it involves sky-diving, rappelling down a mountain, white-water rafting, participating in marathons and triathlons, writing a novel, or lecturing nationally to large audiences about the vagaries of ERISA.


Seth is committed to serving disabled individuals. He is proud of his work in prominent organizations such as the American Association for Justice (AAJ), the Tennessee Bar Association (TBA) and Hospice. Seth is past-Chair of both AAJ's & TBA's Disability Law Sections, past-President of the Chattanooga Trial Lawyers Association, a 2-time recipient of the Pro Bono Excellence Award, and a 7 year member of the Board of Directors for Hospice of Chattanooga.
