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.

I saw Dr Diwakaran while in the hospital for a endoscopy. I found him to be very nice and informative. He explained before hand what to expect and afterwards the results and we would wait for the biopsy to discuss it but not to worry everything looked fine. The questions below do not pertain to me.

Caring and communicative
Dr. D treated me with respect and care. I was a patient and not just a passing person through his office. The way he spoke with other patients, including me, really demonstrated that he is treating a person with gastric issues and not gastro issues only. I mean he treats people with care and compassion.

Dr Diwakaran was very knowledgable and explained the findings from my tests and his evaluations to my level of satisfaction. He was very thorough and was not content to pass my symptoms off without some explanation. He ordered tests colonoscopy, endoscopy and eventually MRI until he was able to find out my condition (Pancreas divisum, congenital defect of pancreas). I would recommend him to anyone.
