He serves as the chair of the Department of Neurology and is the Carmen Castro Franceschi and Gladyne K. Mitchell Neurohospitalist Distinguished Professor.

    Dr josephson is a remarkable physician. Care empathy and medical knowledge and communication were outstanding. Focus was on the brain but Dr. Josephson also saw problems with my blood chemistry (anemia) and recommended attention to possible colon bleeding as from polyps and need for me to get a colonoscopy.

    Dr. Josephson is amazing. I've had a lot of doctors over the years and I can easily say he's by far my favorite ever. He combines his amazing personality with his brilliance in his field to deliver an extremely rare patient experience. He has made my journey with SCA-3 much more enlightened and tolerable.
