Extraordinarily knowledgeable and compassionate as well...I am filled with gratitude that I am under the care of Dr. Warner. I have a complicated problem with my shoulder pain and Dr. Warner is guiding me through these complexities as I see surgeons for different health issues so we can make a decision about shoulder replacement.

Dr. Warner was extremely knowledgeable with a very pleasant personality. He answered all my questions and addressed any concerns i had in a very calming manner. There was absolutely no rush at all in my visit. In fact, I felt like I could've been his only patient of the day. That was very nice.
