Upon completing his GI fellowship in 1988, Dr. Rubin was asked to help build a new endoscopy suite and start a gastroenterology service at New York Presbyterian’s Allen Pavilion in northern Manhattan. From this early stage in his career he was in a clinical leadership position, responsible for the gastroenterology and endoscopic services at the hospital as well as training all rotating fellows from Columbia. Concurrently, he began to build a successful Gastroenterology practice in Riverdale and Manhattan.
By the mid 1990’s, Dr. Rubin’s clinical activities began to shift to the main medical center coincident with his election to the Board of the Society of Practitioners of the Presbyterian Hospital. He was elected President of The Society of Practitioners in 1998. In that capacity, he helped found the Columbia Presbyterian Physicians Network, served on the Board of Columbia-Cornell Care and represented the entire faculty.
Dr. Rubin developed a successful upper eastside practice while continuing to be actively involved in the teaching program at Columbia University Medical Center. His areas of research include celiac disease, inflammatory bowel disease, gastrointestinal bleeding, Clostridia difficile enteritis capsule endoscopy and Double Balloon Enteroscopy.
In 2008, he was appointed Director of the Gastroenterology Service and Fellowship Program Director at New York Presbyterian Queens, Weill-Cornell Medical College. Under his direction the program thrived and won several national and regional research awards.
Dr. Rubin maintains offices in Manhattan and Queens where he sees patients with a broad array of digestive problems.
