Dr. Maureen A. Lefton-Greif, M.A., Ph.D., CCC-SLP, BCS-S, is a Professor of Pediatrics, Otolaryngology Head and Neck Surgery, and Physical Medicine and Rehabilitation at the Johns Hopkins University School of Medicine. Her areas of clinical expertise include feeding/swallowing development and disorders. Certified in swallowing and swallowing disorders by the American Speech-Language Hearing Association, her research focuses on standardization of fluoroscopic images from bottle-fed children with dysphagia and respiratory-swallow coordination in progressive diseases with pediatric origins.
Dr. Lefton-Greif co-authored the book dedicated to Videofluoroscopic Swallow Studies in infants and young children. She is a board certified specialist in swallowing and swallowing disorders, and serves on the editorial advisory boards of the Journal of Dysphagia, the Canadian Journal of Speech-Language Pathology and Audiology, and American Journal of Speech-Language Pathology. She is an active member of the Dysphagia Research Society.
As a nationally and internationally renowned clinician, Dr. Lefton-Greif has served on multidisciplinary, graduate education, and clinical practice guidelines committees. Her work has changed standards of clinical care including diagnostic, surveillance, and management protocols; improved the outcomes and survival of affected children; and resulted in clinical referrals beyond the local/regional area. Her clinical opinions, expertise, and instruction have been requested here and abroad.

Research & Publications
Dr. Lefton-Greif’s research focuses on standardization of protocols and images from bottle-fed children with dysphagia and respiratory-swallow coordination in progressive diseases with pediatric origins.
Her publications were the first to identify the presence of oropharyngeal dysphagia in children with unexplained respiratory presentations; identify dysphagia as a significant contributor to respiratory compromise in Ataxia-Telangiectasia, which is the leading cause of death and had been previously attributed to immunologic problems; and report on a novel scale that quantifies the impact on caregivers of feeding/swallowing problems in their children.
