Dr. Koo is very thorough. He asks a lot of questions to make sure he understands your health issue and is willing to work with you to satisfy your needs. I would highly recommend Dr. Koo to anybody in need of a gastroenterologist.

They got 5 stars for doing their job. I was pre-screened by 3 minute phone call at home the day before. I was taken on time. My doctor remembered my case, answered all of my questions and the scheduling of the next appointment went very efficiently. This is what I want and don't always get.
