The Patient Rating score is based on responses given during the CAHPS Patient Experience Survey.Responses are measured on a 10 - point scale, with 10 being the best score. These scores are then translated to a 5 - point scale in order to display results in a 5 - star rating.Comments are also gathered from the same survey and displayed in their entirety with the exception of any language that may be considered slander, libel or contain private health information, which will be removed prior to publishing the comments.

He drew diagrams to explain what was going on in my body & what his suggestions would be for later.

I have tremendous respect for Dr. Ong; his confidence & knowledge put me at ease

The doctor did not do a physical exam of any kind. I felt this appointment could have been a phone call or video chat.

He puts things into perspective and he's funny.

I have recommended two other patients currently under the care of Dr. Ong
