Welcome to Triborough GI, your trusted gastroenterology specialists! 

At Triborough GI, our specialists support the overall health and well-being of our neighbors from across greater New York City. With four locations across Brooklyn, the Bronx, and Staten Island, access to our seven board-certified gastroenterologists is within reach. Our doctors also boast additional expertise as hepatologists and obesity medicine specialists. 

The considerable expertise of our professionals is complemented by sophisticated technologies. Together, these capabilities allow us to provide the latest treatments and services. Our specialists prioritize therapies that are precise and are associated with minimal risks or complications and have predictable healing processes. 

We specialize in preventing, detecting, treating, and managing various conditions that affect the digestive system. Our team is trained to accurately diagnose and effectively treat issues such as irritable bowel system (IBS), celiac disease, hemorrhoids, Hepatitis C, peptic ulcers, colon cancers, gastritis, GERD, heartburn, H. Pylori bacteria, rectal bleeding, and other problems related to the GI tract and biliary system (liver, gallbladder).

The organs and systems affected by these conditions play vital roles in basic functions – from how nutrients in our food are absorbed to how waste is removed from the body. By restoring healthy function, we get you back to leading your fullest life. This process starts with early detection. Our range of services on this front include:

These diagnostic tools are multi-functional; we can use the likes of an endoscope to take tissue samples (biopsies) and perform procedures like removing polyps, and masses and relieving blockages. We use all our available tools to come up with a comprehensive, individualized, treatment plan.

Additionally, our specialists provide guidance on weight management, nutrition, and lifestyle interventions. Depending on your needs, these recommendations can be central in treating symptoms and conditions, preparing you for a successful procedure, and ensuring a healthy recovery. 

The pathway to better health is through your gut. We welcome your questions and encourage you to bring your concerns to our specialists, at Triborough GI. With four locations across metro NY, one of our gastroenterologists is sure to be close by.
