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.

Should not be an er doctor
She is very slow handling cases in the hospital. Even the staff were not happy how my case was handled. She spent more time on her computer than anything else. Got into the er at 10:00pm not released till after 3:00am !! The whole time was waiting for her to release me. I already knew my diagnosis from the nurses since 10:45pm.

We had my father in the ER over the weekend after 2 falls. He was unable to walk on his own, upper respiratory infection, dehydrated, low bp and low sodium. When family inquired why he was not admitted at least for observation, she became very defensive and rude and would not listen to families concerns or requests for more observation. First time we have ever received such a poor doctor at Progress. If we need to go to an ER and she's at Progress, we will go elsewhere.

Wife cam into ER was admitted for extreme abdominal pain and spasms and was reeling in level 10 pain. It was over 2 hours before she was seen by the doctor. I asked at least 6 times at desk with no response. Finally she came in with an attitude and asked 4-5 simple questions, no exam - left and finally let the nurses give her so thing for the spasms and something to relax her. She is obviously burned out and needs to find another occupation! This was a disaster! She needs to go!
