Need to give patient advice or recommend automatically, not waiting patient to ask for. It will be better if doctors can offer more information.

Your doctor has a good reputation, and I am hoping we are successful in resolving the issue. He was not a strong communicator and seemed very busy. I had to ask the nurse/assistant questions after the procedure to ask the doctor after he left the room. I guess you all are overwhelmed by patients? And I got no explanation for why I wouldn't need meds or packing or anything. I had to ask but still don't understand what all to expect next.

Dr.Koller was very kind and listened to me, he took time and I did not feel he was rushed even though he had other patients waiting. The procedure was timely and gentle.
