David's practice areas include Family Law, Business Litigation/Formation and Public Sector Law.“The depth and diversity of our services set our firm apart from others. It’s rare that clients can go to the same source for a divorce, business lawsuit or formation issues, estate planning or criminal defense and be assured of effective representation in each matter. Our lawyers are equally skilled in transactional matters and courtroom litigation, and extremely knowledgeable in a number of Civil, Corporate and Criminal legal matters.”

A seasoned Litigator and dedicated Public Servant, David L. Cook’s professional and community service roots date back to his teenage years.

“I developed a strong interest in law while still in high school, and I was also interested in public service,” David recalled. “I learned that a large number of State Legislators were also attorneys. As I began college, I firmly believed having knowledge of one (law) would help me with the other (Public Service). "

“One of my mentors, R. L. Anderson, who was also my High School counselor, helped me get a part-time job in Harold English’s office my Senior year,” he continued, referring to a long-time Tarrant County lawyer. “This experience worked out great and solidified my interest in practicing law. Mostly because I saw that Mr. English was really making a difference in other people’s lives.”

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.

“I enjoy the challenges of both jobs and how they often complement one another,” said Cook. “I also like the fact that I’m following the example and tradition established by our Firm’s Founder, Senator Chris Harris.”

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.  

“What I find rewarding is that even though I’m usually working with someone at their lowest point in the beginning, I can almost always guide them through the process in such a way that they end up in a much better place than where I found them,” he said. “I feel like it’s a Practice Area where I can make a positive impact and a lasting impression.”
