I visited Dr. R. For a consultation about potential surgery for an ulcer.  He was excellent!  He was familiar with  my situation and explained everything very clearly.  He is an highly effective communicator!  Plus he seems eminently knowledgeable, listened carefully and patiently to my questions and was kind.  I give him the t rating and while I hope to avoid surgery and therefore not see him again :-) I would absolutely trust him and recommend him to others.
