Speedy, efficient, and competent -- from the initial call to make an appointment to getting in to the actual health service rendered.
Dr Koo is terrific. I wish that someone would talk to cataract patients a day or two BEFORE the cataract procedure to tell them what to expect and what prescriptions to fill BEFOREHAND. I am not about to drive to a pharmacy after the procedure, and THE CLINIC SHOULD NOT ASSUME that everyone has someone at home to help them. That could have been a major problem, but Dr. Koo worked out a solution.
