Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

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

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

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

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

While Dr. Ong is a nice guy I find the office chaotic at best. I have no confidence in him or the practice anymore. I do not trust them. Gunakula did not have me numb before he went into my femoral artery and didn't care and Dr. Ong allowed his mom to do my cardiac cath in my wrist without asking if it was OK. Informed consent goes a long way. I get the chills now when I think about this place. I won't even tell you about some of my test experiences there.
