Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Dr. TeoOng was very professional and explained my bloodwork results. Always patient, caring and listens to my concerns. Megan who took my weight and blood pressure was very nice and friendly. Enjoyed my visit.

Dr. Ong is knowledgeable and always very courteous. Office staff is also courteous however, the time to be seen could be improved. Considering some of these patients are seniors and diabetics, waiting an hour or more might be too much. I usually accompany my elderly parent who has other medical issues and normally has to wait an hour or so after blood pressure and weight are taken.

This doctor is the best!!! He is laid-back, nice, and he actually listens. He doesn't look like he's in a hurry--like most Dr.'s. He sits back and listens, then he explains things clearly and tells you what he can do. Also, his staff is super..... nice!!! The only downer about the whole visit--is that his waiting room is small, but I have been in smaller. So, I definitely recommend this doctor!
