“Dr. Nancy Diaz is a great clinician, always prompt to interact with me via the patient portal and willing to work with me to adjust treatment of my Parkinson's disease. But I believe she is the only movement disorder MD or DO neurologist on St. Luke's staff. When I started treatment with St. Luke's neurology, there were three movement disorder MDs and an MD who did deep brain stimulation. Dr. Diaz is probably being overworked.”
