The Dr. And her Fellow were so kind and allowed me to ask all my questions. This is the first time I've felt heard and understood after visiting multiple doctors prior to this visit at Vanderbilt. I did not feel rushed.

Dr. Coo is one of the kind and caring doctor I ever had. She cares about her patients like her own family. She is a very warm and pleasant doctor. I would never be able to think any other doctor for me.
