David L. Cook

Managing Partner

David is a knowledgeable attorney who provides very good counsel in conjunction with timely client communication. I always knew where we were headed and how we were going to get there. And get there we did!


David’s practice areas include Family Law, Business Litigation/Formation and Public Sector Law. “A seasoned Litigator and dedicated Public Servant, David L. Cook’s professional and community service roots date back to his teenage years. He developed a strong interest in law while still in high school, and was also interested in public service. He learned that a large number of State Legislators were also attorneys. As he began college, he firmly believed having knowledge of one (law) would help him with the other (Public Service). Today, David is actively engaged in the pursuit of both of his passions: He’s the leader of Harris Cook’s daily operations, a prominent Family and Business Law attorney—and he’s also the Mayor of Mansfield, a post he’s held since 2008. David was admitted to the Texas Bar in 1997, following his graduation from Texas Wesleyan University School of Law, which is now known as Texas A&M University School of Law. He completed his undergraduate work at Stephen F. Austin State University, where he received a degree in Public Administration. He’s since become one of the most sought-after Family Law attorneys in Tarrant County, a specialty in which he’s Board Certified. Within that discipline, he specializes in cases that involve Complex Division of Assets or Contested Child Custody matters, and often finds himself representing business owners.
