Dr. Chung-Kah Koh is one of the most knowledgeable doctors I have. He knows very much about my illnesses and about my health. Can't really get into my health and know what to say and do. He answers my questions in a way that I understand and I can ask him questions where he answers me where it doesn't seem like I am bothering him and he is a very good doctor. He is one of the best that I like going to. I feel very comfortable with him. I am very happy he is my doctor and he knows a lot.
