Overview
Dr. Charlotte Sumner is a Professor of Neurology and Neuroscience at Johns Hopkins University School of Medicine. Dr. Sumner cares for patients with genetically-mediated neuromuscular diseases. Her practice is notable for a focus on individuals with inherited neuromuscular disorders of peripheral nerves and motor neurons, including spinal muscular atrophy (SMA) and Charcot-Marie-Tooth (CMT) disease. She co-directs the Johns Hopkins Muscular Dystrophy Association Care Center, the Spinal Muscular Atrophy (SMA), and the Charcot-Marie-Tooth (CMT) clinics, which deliver multidisciplinary clinical care, engage in international natural history studies, and provide cutting edge therapeutics. Dr. Sumner’s research focuses on developing treatments for degenerative disorders of motor neurons and peripheral nerves. Her laboratory uses human tissues and induced pluripotent cell lines, mouse models and cultured cells to characterize disease mechanisms and develop treatments. Dr. Charlotte Sumner received her medical degree from the University of Pennsylvania School of Medicine following undergraduate studies at Princeton University. She completed internal medicine internship and neurology residency at the University of California San Francisco, after which she returned to the east coast for a neuromuscular fellowship at Johns Hopkins and a neurogenetics fellowship in the Neurogenetics Branch at the National Institute of Neurological Disorders and Stroke. She joined the neurology faculty at Johns Hopkins in 2006.
Her clinical expertise encompasses Hereditary Ataxia and Gastrostomy.
Dr. Sumner is board certified in American Board Of Psychiatry And Neurology. She is actively involved in clinical research, co-authoring 97 peer reviewed articles and participating in 2 clinical trials. Dr. Sumner is currently accepting new patients.

Johns Hopkins Outpatient Center
Arens Taga is a neurologist specializing in neuromuscular diseases, with a particular focus on amyotrophic lateral sclerosis (ALS) and other motor neuron diseases. His clinical work aims to improve the quality of care for patients with ALS through biomarker-based, precision medicine approaches that refine disease stratification and facilitate more targeted and efficient enrollment in clinical trials. As a clinician-scientist, Dr. Taga uses patient-derived induced pluripotent stem cells to model ALS, uncover novel disease mechanisms and identify therapeutic targets that are translatable to clinical trials. In recognition of his work in ALS, Dr. Taga was awarded the 2025 Richard Olney Clinician Scientist Development Award, which honors early-career physician-scientists dedicated to advancing ALS research. Dr. Taga earned his medical degree from the School of Medicine and Surgery at the University of Parma, Italy, where he also completed his neurology residency. He subsequently trained at The Johns Hopkins University, completing a postdoctoral research fellowship in the neuromuscular division, an internal medicine internship, a neurology residency and a neuromuscular clinical fellowship. Dr. Taga is highly rated in 6 conditions, according to our data. His clinical expertise encompasses 15q11.2 Microdeletion, Primary Lateral Sclerosis, Amyotrophic Lateral Sclerosis (ALS or Lou Gehrig's Disease), and Cluster Headache. Dr. Taga is board certified in American Board Of Psychiatry And Neurology.
Johns Hopkins Outpatient Center
Dr. Ricardo Roda earned a combined MD/PhD degree from University of Rochester and completed an adult neurology residency, followed by a clinical neuromuscular fellowship at Johns Hopkins University School of Medicine. During residency, Dr. Roda developed a special interest in both auto-immune disorders and genetic disorders. Following residency, he spent three years in neurogenetics branch of National Institute of Neurological Disorders and Stroke (NINDS) working with Dr. Craig Blackstone, focusing on the use of the newer DNA sequencing techniques in genetic diagnosis, and in establishing genotype/phenotype correlations neuromuscular disorders. His current clinical interests include developing testing strategies for undiagnosed genetic disorders and myasthenia gravis. Dr. Roda is highly rated in 3 conditions, according to our data. His clinical expertise encompasses Hereditary Spastic Paraparesis, Thymidine Kinase 2 Deficiency (TK2d), Hereditary Ataxia, and Ptosis. Dr. Roda is board certified in American Board Of Psychiatry And Neurology. Dr. Roda is currently accepting new patients.
