Have heard good things about this doctor and I found out myself that he is that good. You feel his genuine interest in knowing your medical situation and doesn't make you feel rushed during the consultation. Other doctors try to rush through your scheduled time. This doctor works efficiently and with concern. May he continue to be this great carer of the sick.
