I had a great appointment. It was timely and very long.. We discussed everything I wanted to and more. I found Dr. Schmahmann to be very thorough medically, but he also had a breath of knowledge beyond the medicine. There is no one where I live like him so I was very appreciative to be able to be there.

Dr. Schmahmann is outstanding with his problem analysis and relates well with his patient. I'm very happy to have him as our doctor. He will run late because he's taking the needed time to take care of others. It's not a problem, he takes extra time with us as well, running late for his dinner.

I'm a physician myself and the doctor on this visit was meticulously careful, exceedingly well trained, very thorough and textbook admirable in all ways. My only criticism is that he was about to leave the country on the next day or shortly thereafter, and I never got a chance to have a leisurely and complete conversation with him about the findings on that visit. Otherwise, he's an example of perfection.

Dr. Schmahmann is the actual best! He is kind, understanding and explains everything very thoroughly. His knowledge of Ataxia is comforting because no one ever seems to know or understand what Ataxia is. I have been to several nuerologist in the past, no one is more caring or knowledgeable as he is. I consider him a blessing.
