Samuel Ruiz, MD

My decision to come to UTHealth Houston was easy. I was looking for a prestigious institution with a great volume of cases to maximize my training, located in a nice, warm, metropolitan city. This program has all three! The opportunity to practice at the world-renowned Texas Medical Center and Memorial Herman, one the busiest Trauma centers in the US, makes UTHealth Houston the best place to be. In addition, the support of the program, faculty, and staff makes you feel right at home.
