Dr. Dym is in practice as a board and neuroradiology CAQ-certified neuroradiologist who did his fellowship training at Yale New Haven University Hospital and radiology residency at Lenox Hill Hospital in New York City. Until 2020, Dr. Dym was Medical Director and member of the quality assurance team for one of the largest radiology practices in the country. Through this he has reviewed hundreds of misinterpreted neuroradiology studies over the years. This exposure has led him, as an expert in misdiagnosed studies, to lecture extensively regarding medical missed findings and errors. He was recently an advisor for both Nines Radiology and Essential Radiology and is currently a staff Neuroradiologist and Chief of Radiology Quality at Overlook Hospital, helping manage the Neuroradiology section associated with the largest Neuroscience center in New Jersey.
