Dr. Liu knew that I was apprehensive about the procedure but he talked to me and reassured me and it was over before I even knew what was happening. He offered other services but never pushed - just let me know that they were available if I ever wanted them. I would highly recommend his services.

It is really a long wait for appointments both time before and usually waiting to be seen that day. I don't feel receptionists really pay attention to patients but the providers themselves are excellent

My visits are very simple when no cancer is found. The Doctor examines me and does a simple treatment and I get another appointment and I leave.
