All Island Gastroenterology & Liver Associates is a Long Island-based medical practice founded in 1995. The team specializes in screening, prevention, diagnosis, and treatment of gastrointestinal, liver, and nutritional disorders, combining advanced medical technology with professional, personal, and compassionate care.

The practice offers a broad range of diagnostic and therapeutic services, including colonoscopy, upper endoscopy, capsule endoscopy, ERCP, flexible sigmoidoscopy, and lactose intolerance breath testing. Its care addresses conditions such as celiac disease, constipation, GERD, hemorrhoids, inflammatory bowel disease, and irritable bowel syndrome. Patients can also access diet and nutrition resources, as well as in-office FibroScan testing, a non-invasive way to assess liver tissue and detect fibrosis.

All Island Gastroenterology emphasizes colorectal cancer prevention and screening, and provides patient resources such as forms, preparation instructions, insurance and billing information, and frequently asked questions. With multiple locations and appointment-booking and patient-portal options, the practice aims to make specialized digestive and liver care accessible and supportive for patients across Long Island.
