He may be a good doctor. But it is impossible to get an appointment with him even after your tests show him you have a health issue that needs immediate attention. I walked around for three months with a serious issue waiting for my appointment. He had the tests and never called to bring me in earlier. There is hardly any way to talk to human being who gives a damn about you as a person. Everything is through the portal. But you need a pin to access the portal. And no one answers to tell you how to get it.

Dr. Guan has always been a great doctor. He’s personable, listens to my biggest concerns and is all around a great doctor.

He is always pleasant, patient, knowledgeable. Although on this visit I felt the after appointment instructions were a bit confusing. I needed more clear, precise information.
