Went to see gastroenterologist Dr Ooi for my husband back in June 2024. Rude, condescending manner especially after knowing that both of us work in the medical line. I am myself a doctor and that somehow made things worse. We waited for hours for our first visit patiently only to end up getting a subpar service my a fellow physicians in the same work line as mine. I regretted visiting this gastroenterologist. Wasted our time, wasted our time off from work and of course our money.
