McLane was born and raised in Victoria, Texas. The son of a cattle rancher, McLane learned early on the value of hard work. In high school, McLane was selected to study abroad in Argentina for six months. It was there he discovered his passion for travel and learning. McLane went on to earn his Bachelor of the Arts in Anthropology, minoring in Sociology.
After college, he spent some time trying to figure out what to do with his life, working on the family ranch in the meantime. Shortly after that, McLane applied to and was accepted into Baylor University School of Law. As a first year law student, McLane discovered his passion for criminal law, earning top marks in his Criminal Procedure courses. In his last year of law school, McLane participated in the rigorous practice court program at Baylor. Despite the incredibly demanding course load heaped onto practice court students, McLane excelled, actually making the Dean’s List during the second, critical stage of the program. After law school, McLane took the Bar Exam, passing on his first attempt. Once licensed, McLane moved to west Texas to begin working with Tommy Hull.
