Ramirez, 159 S.W.3d 897, 912 (Tex.2004). Here, Dr. Mims testified that he is a board certified neurosurgeon and has been practicing for over twenty years. As a neurosurgeon, Mims, treats back injuries. Mims participated in both of Burke’s back surgeries, and testified that he has performed the same types of surgeries many times on other patients. Specifically, Mims testified that he has performed Burke’s first surgery about 1500 times, and the second surgery about 150 times. Mims took a medical history from Burke and examined him on multiple occasions. The record therefore includes evidence that Burke’s injury was within Mims’s realm of expertise. Cf.
