David L. Cook

David L. Cook is a seasoned litigator and dedicated public servant at Harris Cook, LLP, in Mansfield, Texas, whose commitment to justice and community stewardship began early. As managing partner of Harris Cook, LLP, he directs the firm’s daily operations while maintaining a thriving practice in family, real estate and business law.

Board-certified in family law by the Texas Board of Legal Specialization, Mr. Cook focuses on complex asset division and contested child custody disputes – often representing business owners navigating sensitive personal and financial stakes. Over the years, he has become one of Tarrant County’s most sought-after family law practitioners.

While still a high school student, Mr. Cook discovered the power of the law to transform lives, and he enthusiastically cultivated a strong desire to serve the public. These early convictions guided his academic path – he earned a bachelor’s degree in public administration from Stephen F. Austin State University and then studied law at Texas Wesleyan University School of Law (now Texas A&M University School of Law), graduating and joining the State Bar of Texas in 1997.

Beyond the courtroom, Mr. Cook’s passion for public service has shaped his community leadership. He served as Mayor of Mansfield from 2008 to 2020, steering initiatives that fostered economic growth and improved quality of life. In 2020, he took his commitment to the legislature, winning election to the Texas House of Representatives. There, he leverages his legal background and experience to craft policies that promote fairness and opportunity across the state.

Mr. Cook’s dual roles as attorney and legislator exemplify his conviction that the practice of law and the pursuit of the public good go hand in hand. His career stands as a testament to the lasting impact one individual can achieve when passion for justice and commitment to community converge.
