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.

Horrible beside manner and patient care
I was admitted from the ER. in a hospitalStay. The next morning when she went to see me as the Attending (Physician Consultant) as soon as she greeted me she was extremely rude . She asked “How are you feeling” and I answered “doing good” - immediately her response was “THEN WHAT ARE YOU DOING HERE?” When she asked me a question and I was answering she looked at me intently into my eyes without blinking and it was an intimating and scary feeling. Very very Poor bedside manners. When I asked her if she had seen my chart - her answer was somewhat! Well she didn’t have answers to my questions, what test where schedule for me that day that I can not eat, didn’t go over with me the blood test that already had been read, and when the nurse was trying to get some work orders, she flat out said she had other patients to see and was very busy to write in my chart, where the nurse said I can do that for you if you give me the orders.
