Background
How he got here
Dr. Achillefs Ntranos is a board-certified neurologist and MS specialist known for thorough evaluations and a compassionate approach. Born in Athens into a family of biologists, he studied at the University of Athens Medical School before training in neuroimmunology and multiple sclerosis research at Johns Hopkins University.
He completed his neurology residency at Mount Sinai, where he served as Chief Resident, followed by a fellowship in multiple sclerosis and demyelinating diseases. He went on to become an Assistant Professor of Neurology at Mount Sinai, publishing peer-reviewed research in journals including Brain and Neurology.
He founded Achilles Neurology Clinic in Beverly Hills in 2022 so visits could run as long as they need to, not as long as a hospital schedule allows. He specializes in MS, autoimmune neurology, neuropathy, and headache, blending research-driven insight with personalized treatment plans.
It is more important to know what sort of person has a disease than to know what sort of disease a person has.
Languages: English and Greek. Licensed in California.
