I didn't like Dr Harrmon showyup to my consultation wearing a mask. Neither one of us were contagious and he asked me if I wanted him to wear a mask, I told him it was not necessary. After that, I was very satisfied and felt very confident with Dr. Harmon.Overall my experience was great and Dr Harmon took be through exactly what I would be going through.
