Just to share my experience on Koay Cheng Boon. He is not very good or professional in my opinion. I had few ocassions of throat irritation and nausea in the morning few years back. I went in and out of his clinic for few months. Always ask me to come back in 2 weeks.

The symptons persisted after the few visits. Never in his mind that they could be caused by something else. Only until the symptoms getting worse with heart burn, then I decided to see a Gastrologist. I was finally diagnosed with gastro acid reflux problem.

My conclusion is he is jeopardizing patient health and wasting my time, money and health. He could be too indulge in his discipline and too commercial to get hold on money. Whatever it is he is not very good.
