Dr. Zimmer listened to my description of symptoms and zeroed in on a possible diagnosis in less than ten minutes. A blood test further supported her diagnosis. Treatment began immediately as I have a potentially dangerous inflammation of arteries in my head. I am feeling better in two days and will continue treatment with a rheumatologist on Monday. Dr. Zimmer is brilliant. She may have saved my vision from a condition I had never heard of.

very satisfied with my discussion regarding my health issues
star
Feb 5, 2020
I came in because I was struggling with asthma. She said there was nothing she could do for me and sent me to the ER. She said my lungs were clear and my oxygen was 99. The ER did nothing more than give me a prednisone shot and prescribe prednisone and cough suppress. The ER staff was upset that she sent me to the ER risking further illness. I was upset for this reason and because it was a waste of my money and time. I feel that and IM Dr should be able to handle a continued asthma flare up post illness.
