I would recommend Dr. Koo because he had a great patient-physician relationship. I truly believe that a good patient-physician relationship is one of the most unique human experiences I had, and it is undeniably integral to my health. Dr. Koo connects all my other team of doctors together when I’m having any type of surgery or test. He follows up with me when I have questions, tests, and/or surgeries. He knows my history and my family history and when I need to make a medical discussion, we make it together.
