Yes, I found Dr. Singh just a marvelous human being. He was very attentive. He was very sympathetic. He was thorough in talking about the various options that I have regarding my particular situation.

Dr Sing is a brilliant clinician with an easy and friendly manner. He conveys clinical findings into lay language and understands the concerns and impacts of life style changes on his patient. For me, the life style change is less coffee...way less coffee. Dr Sing understood this to be a huge change. We had a few laughs about it as he displayed a good sense of humor. To sum up, an excellent encounter and I recommend him highly to other patients.
