Dr. Walker is very talented in profession, I just had a complete hip replacement surgery and he walked me through all aspects of the surgery process, it was very painful but all went well. He’s nurses and physical therapists were very helpful and kind. I am so grateful and now I am a completely new person, thank you Dr. Walker
