Huntington's Disease Center at Johns Hopkins
The Huntington’s Disease Clinic at Johns Hopkins has been listed as a Center of Excellence by the Huntington's Disease Society of America (HDSA) since the list was first published. In fact, it was the first Center so designated. We strive to balance excellent clinical care, research, and teaching with an expert team of physician/researchers, research professionals, social workers, and support staff.
