Will is a 2021 graduate of University of Texas School of Law.  Will graduated with honors and joined the Order of the Coif for being in the top 10% of his class. An avid and successful participant in mock trial, Will was inducted into the Order of the Barristers, an award bestowed on the top ten advocates of each graduating class. 

From listening to his father practice as a small child, to being captain of the Debate Team in high school, to learning to virtually argue via Zoom in law school, Will’s entire life prepared him to litigate. Within weeks of being licensed, Will cross examined a doctor, a lawyer, and argued an entire Rule 12 motion to show authority. Will primarily works on the firm’s family law cases, but he enjoys the smorgasbord of Sullivan & Cook’s civil litigation practice, especially the niche equine lawsuits.

Will is engaged to Elizabeth Vineyard whom he met during his seven years at the University of Texas. Will learned being a football fan of the University of Texas and the Dallas Cowboys only causes pain, so he now spends his falls hunting. Will guides upland bird hunts in Texas and Rocky Mountain Elk hunts in Colorado on the Double A Ranch. He owns and trains Chesapeake Bay Retrievers. His dog, Hellie, retrieved over 1,400 birds before turning two. Will hunts internationally with his father from the Arctic Circle to the southern tip of Africa. Will has hunted on safari in southern Africa over ten times. When Will isn’t hunting or practicing law, he rides horses. 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.
