Dr. Joshua Sloan completed his Internal Medicine residency and Gastroenterology fellowship at Einstein Medical Center in Philadelphia, PA. After completion of his general Gastroenterology fellowship under Dr. Philip O. Katz, former American College of Gastroenterology President and Esophagologist, he went on to complete an additional fellowship in Gastrointestinal Motility and Neurogastroenterology at the Johns Hopkins University School of Medicine. He then created a dedicated esophageal clinic and was the Director of the Dysphagia Clinic at Johns Hopkins University School of Medicine. His clinical interests broadly include esophageal motility disorders, eosinophilic esophagitis, radiation induced esophageal dysmotility, and gastroesophageal reflux disease. Dr. Sloan’s research aims are to better understand and characterize esophageal motility abnormalities as well as to improve our understanding and management of radiation induced esophageal dysmotility.
