    Dr. Ermann is the best Rheumatologist I have ever seen. His knowledge, ability to listen, ability to explain things, and mostly I trust and respect his advise and opinion.

    My experience with Dr. ERMANN is always amazing. He's great. He listens to everything I have to say. He answers all my questions. I never feel rushed. I feel like he really knows what he's doing, which is obviously important with a doctor, and is by far probably one of my favorite doctors out of all the doctors I've ever seen. He's just a really good doctor and just a decent human being and just has great, just great personality and shows that he cares. So that's it.

    This was the first time I had been seen by Dr. Ermann. He obviously spent some moments looking over my chart because he seemed to be well acquainted with my history, which felt very comforting. I thought he was skillful and I am comfortable seeing him in the future.

    I can't say enough good things about my provider. He was extremely understanding and kind. He is the only provider I have seen where I felt he was listening without judgement and his goal was to provide the best care possible for my illness. If I lived closer, I would be grateful to have him as my rheumatologist.

    Dr. Ermann is a tremendous doctor. He takes care and pride in his work. Unfortunately, there wasn't anyone available to take my vitals, but that's okay because he handled it. He did it all himself. He's a tremendous doctor.

    Dr. Ermann is excellent. He is professional, friendly, makes you feel at ease and listens to you. I never feel rushed and I like that he provides options and his opinions on treatment options but allows me to direct my care. I highly respect his bedside manner and knowledge and always feel comfortable discussing my disease symptoms with him. I would absolutely highly recommend him to anyone in need of an excellent rheumatologist.

    Real smart guy, but he had very very short patience, I thought he might've been mad with me. Very hard to read although in the end, he seemed to have a plan so we'll see how it goes.

    Unfortunately Dr Erhmann didn't read my record before the visit. This lead to talking in circles. He contradicted what other doctors told me and left me feeling unheard and confused.
