LEAD ATTORNEY

Relentless is led by Attorney Kyle Mothershead. With over twenty years of experience and a lengthy track record of success, Mr. Mothershead is regarded by many as the best attorney in middle Tennessee for litigating federal constitutional rights claims involving the justice system.

Mr. Mothershead graduated from Vanderbilt Law School in 2002 with several honors, then clerked for United States Middle District of Tennessee Judge Aleta Trauger. Declining the opportunity to seek work with one of the big “white shoe” firms, Mr. Mothershead followed his heart and spent the next eight and a half years as a Metro Nashville public defender. In that role Mr. Mothershead represented both adults and children, and built his core litigation skills and values through countless hours of courtroom experience dedicated to the sacred task of representing others.

In 2012, Mr. Mothershead started his own practice. Over the course of the next decade Mr. Mothershead scored several major successes in federal constitutional rights litigation, most notably by serving as lead counsel in the Rutherford County juvenile arrest and detention class action that later received nationwide attention thanks to the award-winning NY Times podcast “The Kids of Rutherford County". In 2021, Mr. Mothershead founded Relentless as a boutique firm focused on holding the justice system accountable to the Constitution.

Mr. Mothershead resides in Brentwood with his twins, Paul and Cassidy. Mr. Mothershead is extremely dedicated to his children, and spends as much time as he can with them when not leading Relentless.

ASSOCIATE ATTORNEY

Associate Attorney Aaron Rothbaum graduated Vanderbilt Law School in 2017, where he had been a member of the Vanderbilt Law Review as well as a research assistant for professor Robert Mikos. As a law student, Mr. Rothbaum also interned for Mr. Mothershead, doing excellent work for Mr. Mothershead’s clients and laying the foundation for a long-term professional relationship. After graduating Vanderbilt, Mr. Rothbaum clerked for a year with Justice Cornelia A. Clark of the Tennessee Supreme Court. Following that, Mr. Rothbaum practiced criminal defense with the Metropolitan Nashville Public Defender’s office for just over five years. During those years Mr. Rothbaum handled countless criminal cases ranging from minor misdemeanors to the most serious felonies, and gained extensive courtroom, litigation, and negotiating experience.

In addition to his intellectual acumen and courtroom experience, Mr. Rothbaum is fluent in Spanish. Mr. Rothbaum credits his skill to a combination of study and his wife, who is originally from Peru. In their leisure time, Mr. Rothbaum and his wife enjoy travel, hiking Tennessee’s parks, gardening, and spending time at home with their cat.
