We are exciting to announce our newest physician  Dr. Delia Calo,MD, PNS, CNSC.  She graduated from Stony Brook University MedicalSchool, completed her internal medicine residency training at NY Presbyterian–Weill Cornell, and her fellowship in Gastroenterology, Liver Disease and Nutrition at Memorial Sloan Kettering Cancer Center.   She will begin seeing patients August 1st.  

For those of you new to us, we have selected eClinicalworks as our platform.  The patient portal link above allows access. To aid in the transition, our old patients may be asked to fill out some paper work to make sure our computer system has the most uptodate information on their initial visit since our system has been up and running.   We are also excited to offer a new app from 22otter to help walk you through the preparation process for certain procedures. 

Mission Statement 

The primary objective of Brookhaven Gastroenterology Associates is to provide the highest quality of specialty care in gastroenterology, hepatology and gastrointestinal endoscopy for Long Island by creating an environment that encourages compassion, dedication and attention to the safety and individual needs of our patients. 


About Us

For over 40 years, Brookhaven Gastroenterology Associates has been devoted to the diagnosis and treatment of digestive and liver diseases.  All our physicians are board certified in Gastroenterology and treat a variety of conditions from common diarrhea, and  heartburn to diagnosing rare cancers of the gastrointestinal tract.  

Gastroenterology is a specialty dedicated to evaluating the intestines (including the stomach, small and large intestines), liver, pancreas, and gallbladder.  With the aid of fiberoptic technology, extensive portions of the intestines can be examined and biopsied.  Colonoscopy or lower endoscopy has been an instrumental part of the public health initiative of screening for colon cancer.  Over the years we have also adopted the latest technologies including wireless capsule endoscopy, which takes thousands of pictures of the small intestine using a pill like camera, and  Endoscopic Ultrasound that helps better visualize and biopsy lesions throughout the body using special ultrasound guidance.

In addition, we have completed a renovation of our facilities providing modern amenities for our patients as well as state-of-the-art office based endoscopy units where outpatient procedures can be safely performed.  Our endoscopy unit has been accredited by the Association for Ambulatory Healthcare (AAHC). 

At BGA, patients can be assured of our commitment to high quality, cost-effective health care in a respectful and compassionate environment.   Please schedule an appointment and find out why BGA is the right practice for you.
