Very knowledgeable. Doctor came in and spent an hour with us going through my medical history and symptoms.

Takes time with you and listens to what you are saying. I complained to my doctors since 1987 that food stayed in my stomach for days. Dr. Walker sent me for a test after our first visit and gave me a diagnosis. In fact, he called me on a Sunday evening to give the results.

Dr. Walker did my procedure on 9-1. He and his nursing staff were great. I was so apprehensive before the procedure, but they made me feel comfortable through it all. Highly recommend.

Dr Walker and his staff were very courteous and attentive to my questions and concerns!
