Dr Chang has been in the male genitalia business for over 10 years and has provided excellent care for myself and for my sons. Anyone who knows Dr Chang or had the chance to meet will will instantly know why he is the number 1 rated doctor in Vancouver - his bedside manner is excellent, his surgical skills clearly superior, he is transparent with outcomes and expectations, and perhaps more than anything I really got the sense that he cares. I highly recommend Dr Chang if you are considering any kind of male enhancement or other services he provides. Tip: I would recommend Dr Chang over Dr Pollock if given a choice.
