John Warner did an excellent job. He replaced both of my shoulders different times, but each time everything was precise, excellent work, very little scars, good operation, everything works the way it's supposed to work. He got me doing the PT on his follow-up schedule and that's been very helpful rehabbing me, getting the most out of the operation and getting the most flexibility. And anytime I've asked him a question, he's been exact on it and fully knowledgeable and he took good care of me. So I very much appreciate it and he did a great job. So I'd give him an A, A plus. All right. Thank you.

This provider is a very skilled surgeon. I would recommend for his skill. I felt dismissed following the surgery. [redacted] I was evaluated virtually for the rest of my care. [redacted] Questions were possible but I did not feel heard. He had a list of his own questions to guide the conversation. His primary focus was if I was better than before surgery. That is not the only consideration.

[redacted]. My life partner accompanied me to the appointment, and Dr. Warner answered many of my questions before I even had the chance to ask them. [redacted]. Dr. Warner will perform my surgery on October [redacted], and I feel truly blessed that he can do it. Since he focuses exclusively on shoulder surgery, and I am having a rotator cuff repair, I believe that specialization is essential. I also left his office with a complete packet covering every stage, pre-surgery, surgery, and post-surgery, with more information than I had imagined. It gave me great confidence in the process and in being under his care.
