My child also consults Dr Yau. Personally I regretted so much in choosing the clinic. At first I thought it worth to pay 50-60K for Dr Yiu bec he showed his experience in the first two consultations. Then he told me he would work with another doctor Dr Yau to handle the case of my child. However, I found he never handled my child any more. Dr Yau is nice, but he is extremely busy, every time my child has to wait 1-1.5 hr before seeing him. In recent months, my child could not make any appointment on Sat within 1-1.5month. Even after school on weekdays, offer of time slots are limited as Dr Yau has to hold seminars and teach in class.
