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.

Dr. Ermann listened to my concerns, ordered tests that I asked for to see a broader image of my problems, and explained everything to me very thoroughly. When he determined my issue to be outside of his scope of care, he referred me to a colleague who he believes can help me, which I really appreciated

This doctor was wonderful and listened to me carefully and explained everything beautifully. He treated me with respect and kindness. It was such a pleasure feeling so well taken care of. He personally responded to me right away when I asked him a question through the Portal and took a great deal of time explaining everything to me. I highly recommend this doctor!

Dr. Ermann was great, spent a great deal of time with me reviewing my current medical conditions and was very attentive throughout the conversation. He offered a new perspective to my issues and possible new treatment even if technical issues prevented a better evaluation. The trouble getting to office during rush hour was immediately offset by Dr. Ermann and the office staff politeness and involvement. I would recommend this office to anyone.

Dr. Ermann is very bright kind and he listens to you and then he explains what is going on and why you have such pain. He has treated for gout and now he is treating my bad knees. I have been seeing him for a while and I would recommend him to any one because he is the best.
