Dr Walker is thorough and excels in his profession. He stays up to date on the latest orthopedic advances and applies them to his patients. I had a knee replacement and was pleasantly surprised at the lack of pain after surgery and how well the knee works already. I am so pleased with my knee that he will be doing a hip replacement in a couple weeks. I am confident I am receiving the best care possible with Dr Walker.
