Hi Candybaby,
I am currently seeing Dr. Chan and find her very good. She is very friendly, willing to spend a reasonable amount of time with you, and 'go out of her way' somewhat to help, even though she is extremely busy and has many patients. The clinic is actually spearheaded by Clement Ho, who is very well know in this field. However, the waiting list for new patients for Dr. Ho is about one year, so I took the recommendation to see Dr. Chan.
Don't know what her actual success rate is like - I haven't been successful yet, but quite hopeful.
