I had never seen Dr wendy Teo before. But if you are searching for a gynae or obstetrician, you may wish to consider Dr James Lee who has over 10 years of experience and I had womens' health check up done by him. Was not really comfort with a male Doctor though.
Fortunately, he has a staff nurse with him during any procedure.
