Patient Reviews
Sep 13, 2025
We went to the ER because my husband has had a consistent fever for almost a week. He was showing no improvement and, in fact, getting worse. Dr was rude and didn’t listen to a thing that was said. She was set on it being COVID even when the test came back negative. All she wanted to talk about was him getting the Covid vaccine. I also had to open our door to ask the nurse for another gown and she yelled at me to close the door and get in the room. I obliged but could still see her through the window. She then looked disgusted and told the nurse to come and make sure I kept the door closed. There is more but the point is she’s one of the worse doctors I’ve seen in the ER.
