I started seeing Dr Thian maybe 7 yrs ago, and since been back whenever I was sick (don't get sick often *knock on the wood) and even after consulting my employer's list of docs. Funny thing was, I don't live that near to the clinic, maybe 5min walk. In any case, his hold was was rather safe and he's reasosnable. Fyi, when he does house visits, it's a hefty fee.
