Dr. Gruner is very professional. I hadn't seen him in two years and we discussed why I was there on Friday. He is very accommodating because I had been back-and-forth from Florida with Cleveland Clinic and my radiation and so on I felt very very comfortable and he made sure I understood everything he read what the reports said and then he put it in Lehman terms so I could fully understand what I'm dealing with.
