Our gastroenterologists provide diagnosis and treatment for a wide array of gastrointestinal disorders or diseases of the digestive system. This includes the gastrointestinal (GI) tract (esophagus, intestines, stomach) and the biliary organs (bile ducts, gallbladder, liver, pancreas).

“What I love about gastroenterology is the opportunity to make a real difference in patients’ lives. Whether it’s helping someone manage a chronic digestive condition or detecting disease early through preventive care. At PAGNY and NYC Health + Hospitals, I’m able to deliver this care to a diverse patient population while working in a supportive, mission-driven environment.”

From supporting digestive health to performing life-saving screenings like colonoscopies, the work is both challenging and deeply rewarding. At PAGNY and NYC Health + Hospitals, I’m proud to serve a diverse community, collaborate with dedicated colleagues, and make a meaningful impact every day.
