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. Innasimuthu is an excellent cardiologist. He’s been my doctor since 2021 when he performed my TAVR surgery and I went home the next day. He’s patient and explains everything to you. I would recommend him.

I brought my 96-year-old father in for a check-up less than two weeks after he was released from the hospital. He had a 10:15 a.m. appointment. He waited for more than an hour and fifteen minutes in a crowded waiting room to see Dr. I. When he was finally called, he said he was attended by an assistant and never did see the doctor. Was told his next appointment was in December but was not given an appointment card.
