When you are at Dr Reuben's clinic you can ask to see his before and after photos of his treatment. My sister found his treatment to be very good, and honestly she needed to retake the MALAYSIAN IC card photo again because she looks different!!!!! (maybe face become slimmer.... ha ha). As far as i know he works full time......

I think the whitesmile orthodontic clinic also has a facebook page, i don't have the link, just search.... got some info from time to time....
