Dr Chieng is a young and enthusiastic Gastroenterologist that i have never met before. He's perfect and friendly.
My wife has vomiting issue for few years, seeing many specialists, and doing many endoscopies around klang valley. And i read about Dr Chieng from Ampang, i bought her to him in December....diagnosed Acalasia (which never found by other gastro specialists during the scopes before), and dilatation done under the scope, she's well now. Thanks God. What a super doctor he is!
