Dr. Walker did a great job on my hip replacement. More importantly to me is that he listens to my concerns and I have been pleased to have sincere, real & informative feedback from him!

Dr. Walker has already done two complete hip replacements on me. He is so down to earth and easy to understand when he explains to me what's going on in my old joints.As long as he's practicing and I am able to get myself to the OI, Dr. Walker is definitely who I will continue to see for my major joint problems. Thank you Dr. Walker for caring about your patients the way you do.

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
