Dr. Joshua Sloan is an Assistant Professor of Medicine in the Division of Gastroenterology and Hepatology at the Johns Hopkins University School of Medicine as well as the Director of the Dysphagia Clinic. In this clinic, he focuses on seeing patients with difficulty swallowing from a number of esophageal problems ranging from motility abnormalities such as achalasia to patients with eosinophilic esophagitis. He also works closely with the Radiation Oncology Department, among others, to improve swallowing after radiation for head and neck cancer. Additionally, he is a member of The Heartburn Center at Johns Hopkins Medicine.

He has completed his gastroenterology fellowship at Albert Einstein Medical Center in Philadelphia, PA where he worked extensively with Dr. Philip Katz, a well-known esophagologist and past president of the American College of Gastroenterology. Following his fellowship he completed an additional advanced fellowship in the study of Motility and Neurogastroenterology at Johns Hopkins Medicine.

Dr. Sloan’s clinical interests include: esophageal dysmotility, dysphagia, eosinophilic esophagitis and gastritis, barrett’s esophagus, gastroestophageal reflux disease (GERD), esophageal strictures, dyspepsia, peptic ulcer disease, and colon cancer screening. His research interests involve gastrointestinal motility disorders with a special focus on the esophagus. more
