I signed that lessen has a lot of patience and explains everything in detail! And if I am not sure of myself, he will speak to my daughter on the phone while I am there. Never seems to be in a rush to his next patient although I know he has many.

My doctor communicated with my gastroenterologist who is not a UM doc. He actually spoke to him. It was very refreshing for the doctors to communicate with each other for my benefit.
