Dr. Tom Crawford has been a member of the Department of Neurology since 1987. He is co-director of the MDA clinic for Neuromuscular Disorders and Neurologist for the Ataxia Telangiectasia Clinical Center at Johns Hopkins. His practice involves general child neurology with a principal interest in caring for children with neuromuscular, neuromotor, and ataxic disorders. Primary research interests involve the basic science and clinical characterization of two important neurologic disorders that affect children: Spinal Muscular Atrophy and Ataxia Telangiectasia. He is also actively involved in the Biology of neurofilaments by characterization of transgenic animal models. He is on the Medical and Scientific Advisory Boards of Families of Spinal Muscular Atrophy, and the Medical Advisory Committee for the Muscular Dystrophy Association. He is the Neurologist for the Ataxia Telangiectasia Clinical Center at Johns Hopkins, which has evaluated almost half of the known patients with this disorder in the United States. Additional specific clinical interests include evaluation and treatment of children with brachial plexus palsies. Dr. Crawford received his medical degree from the University of Southern California. He completed a pediatric internship and residency at the Pediatric Pavilion of the Los Angeles County / University of Southern California Medical Center, followed by a pediatric chief residency. He completed his training in Neurology with Special Qualification in Child Neurology at the Los Angeles Childrens Hospital. He then traveled east to the laboratory of Dr John Griffin at Johns Hopkins for a fellowship in Neuromuscular Disorders. Prior to medical training and Neurology residency, he majored in Psychology and Religion at Yale College. Dr. Crawford has published extensively and presented nationally and internationally. He has an active role in teaching medical students and residents in neurology. In addition, Dr. Crawford has special interest and experience in EMG studies of children and adults. Dr. Crawford is rated as a Distinguished provider by MediFind in the treatment of Nemaline Myopathy. His top areas of expertise are Primary Lateral Sclerosis, Spinal Muscular Atrophy (SMA), Ataxia-Telangiectasia, and Spinal Muscular Atrophy Type 2.

Sarah Neuhaus is a Pediatric Neurologist and a Neurologist in Bethesda, Maryland. Dr. Neuhaus is rated as an Advanced provider by MediFind in the treatment of Nemaline Myopathy. Her top areas of expertise are X-Linked Myotubular Myopathy, Congenital Fiber-Type Disproportion, Tubular Aggregate Myopathy, and Primary Lateral Sclerosis.

Neurologist Payam Mohassel specializes in myopathies, muscular dystrophies, and other hereditary neuromuscular disorders and is the co-director of the Johns Hopkins Myositis Center. Dr. Mohassel obtained his medical degree from the Johns Hopkins University School of Medicine, where he remained for a medical internship, residency training in neurology, and clinical fellowship training in neuromuscular medicine. He then joined the National Institute of Neurological Disorders and Stroke Neurogenetics branch as a clinical research fellow. Dr. Mohassel’s research focuses on translational studies on neuromuscular disorders, and it spans gene discovery efforts, mechanistic studies to identify therapeutic targets, and early phase interventional clinical trials. Dr. Mohassel is rated as an Advanced provider by MediFind in the treatment of Nemaline Myopathy. His top areas of expertise are Amyotrophic Lateral Sclerosis (ALS or Lou Gehrig's Disease), Primary Lateral Sclerosis, Hereditary Sensory Neuropathy Type 1 (HSN1), and Hereditary Sensory and Autonomic Neuropathy Type 2.
