Thomas A. Mars

Tom Mars is an accomplished trial lawyer, a nationally recognized advocate in collegiate sports, and an experienced crisis consultant for companies, executives, and public officials. Tom's office is in Northwest Arkansas.

After graduating first in his law school class and making the top score on the bar exam, Tom began his career as a law clerk to Judge Monroe McKay on the U.S. Court of Appeals. Following his clerkship, Tom spent the next ten years establishing himself as one of Arkansas’ most formidable trial lawyers.

In the 1990s, Tom’s high-profile clients included the Governor of Arkansas. In 1998, the Governor asked Tom to join his leadership team as Director of the Arkansas State Police—the state’s highest-ranking law enforcement position. He served in that capacity for nearly three years before returning to private practice as a trial lawyer in Northwest Arkansas.

Not long after returning to private practice, Tom was recruited by Walmart to manage its vast litigation portfolio as Vice President and Assistant General Counsel. Four months after joining Walmart’s legal department, he was promoted to Senior Vice President and General Counsel and became responsible for all of the company’s legal matters.
