i went there one month back/ sadly it wasn't dr ong sia. it was her disciple as the nurses mentioned.
though its not dr ong the famous doctor, i think first visit for most pple shld be the same, as told by my friend. first visit usually give same breed of medication, then 2nd visit and thereafter they'll start customizing.
one good thing is that dun need queue cos its not dr ong.. i only had 2 patient before me. anyway, my acne stopped breaking out after i use their medication, namely niks acne clear gel, clinda gel, steiva a and their skin recovery skin. scars though, didn't improve much.. i think need laser ba.
btw, dr ong works in maple clinic midpoint orchard twice or thrice a week. its more ex there, but i suppose can make appt and don[t need queue ba. i think i'll go there for 2nd visit onwards.
maple tampines v troublesome sia. still must take bus in. got 2 feeder that goes in bus if i'm not worng. and if u wanna go visit dr ong, best is go there before it opens and queue. if not you won['t get to see her at all!
