Will graduated with honors from the University of Texas School of Law in 2021 where he was an avid and successful participant in the mock trial program. Will joined the Order of the Coif, an honor reserved for those graduating in the top 10% of the class, and he was also inducted into the Order of the Barristers, a recognition bestowed only on the top ten advocates of each graduating class.
From watching and listening as a young child to his father practicing law, to serving as captain of his high school Debate Team, even to having to adapt to virtually arguing via Zoom in law school, Will’s entire life has prepared him to litigate. Within weeks of being licensed, Will cross examined a doctor, a lawyer, and argued to the court an entire Rule 12 motion to show authority. Will sat second chair with Jeff in final arbitrations and bench trials within months of becoming a lawyer and since then as lead lawyer successfully tried cases to the court and prevailed on motions for summary judgments from Tarrant County on paternity to Rockwall County on specific performance for a lot purchase. Will’s practice includes an emphasis on the firm’s family law cases, but he enjoys working on the smorgasbord of the firm’s civil litigation matters, including an ever-growing docket of equine cases.
Will tries cases in all counties of the DFW area, including Tarrant, Dallas, Denton, Ellis, Parker, Collin, Rockwall, and Wise.
Will met his wife, Elizabeth Vineyard Cook, while they were both completing their undergraduate degrees at the University of Texas. Will learned through a lifetime of cheering for the Cowboys and Longhorns that football only causes pain in the end, so now he spends his falls hunting. Will guides upland bird hunts in Texas and Rocky Mountain Elk hunts in Colorado on the Double A Ranch. He also owns and trains Chesapeake Bay Retrievers. His dog, Hellie, retrieved over 1,400 birds before turning two years old. Will hunts internationally with his father from the Arctic Circle to the southern tip of Africa.
When Will is not hunting or practicing law, you will find him on a horse. His first job, other than opening gates, was working for Widowmaker Trail Rides as a wrangler. Will grew up riding a blanket Appaloosa and currently rides his leopard Appaloosa. As a lifetime member of the Appaloosa Horse Club and the Rocky Mountain Elk Foundation, Will supports the beauty of the American West and her animals.
Will and Elizabeth’s son, Hayes, born March 2024, remains a few years away from being the next Cook to join the firm.
