It was very good.
Yes, I wanted to say that the two doctors with whom I dealt were very good and I was very happy with the care and all the nurses have been great, as is the gentleman at the front of the office. So I'm very happy with the way everything has been going. Thank you.
This provider for me, Dr. Zacharias, was wonderful, very competent, very friendly, very caring, very compassionate, very thorough, very professional, and I'm very grateful that I got in to see him finally. The problem is, was it took me six months to get in to see him.
Very caring and informative.
I feel confident in his care
The provider seemed bewildered about my presence, as in wondering why I was there. The original diagnosis that we were given was not what the doctor was telling us in this visit. My tests all came out better than before, and results were normal.
nothing else to say. Everyone was respectful
He was pleasant, helpful and answered all my questions
All good.
the doctor is very attentive and really listens to all of my concerns and questions . He answers all of my questions in a professional manner and in ways that I understand. He is Great.
