About your advocate
TJ Mayes is an experienced trial attorney representing clients in complex personal injury and criminal defense matters. He litigates cases through jury trial, dispositive motion practice, and high-stakes evidentiary hearings, with a reputation for meticulous preparation and persuasive courtroom advocacy.
At his boutique law firm, TJ focuses on serious injury cases, constitutional issues, and fact-intensive criminal matters where credibility, strategy, and narrative control determine outcomes. He is regularly trusted with cases involving substantial factual records, contested expert testimony, and significant legal exposure.
Before founding his firm, TJ served as a senior government official and political strategist, where he worked at the highest levels of legislative advocacy and executive decision-making. That experience informs his litigation approach—shaping trial strategy, refining witness examination, and framing compelling case narratives grounded in policy, procedure, and constitutional principles.
TJ’s background allows him to see cases not just as legal disputes, but as strategic contests requiring disciplined preparation and a clear command of the facts and the law. Clients value his ability to simplify complex issues for judges and juries while aggressively protecting their rights.
In addition to his legal practice, TJ is an active civic leader who serves on public and nonprofit boards addressing healthcare policy, mental health services, and public accountability. His commitment to service extends beyond the courtroom and reflects the values that guide his practice.
