Dr. Zeeshan Ramzan completed four years of gastroenterology training from Temple University Hospital in Philadelphia, which included one year of formal training in the field of gastrointestinal motility (under the mentorship of Dr. Joel Richter and Dr. Henry Parkman). Thereafter, he completed one year of dedicated training in Advanced/Interventional Endoscopy at Northwestern University Hospital in Chicago.  Current clinical and research interests include advanced endoscopy with special focus on its utility in the evaluation and treatment of various esophageal diseases (such as motility disorders, reflux disease, as well as other benign and malignant diseases of the esophagus).
