We are an independently operating gastroenterology group comprised of eight physicians board-certified in gastroenterology.
We have seven conveniently located offices in central New Jersey, including New Brunswick, East Brunswick, Somerset, Edison, and Englishtown as well as a south New Jersey office located in Cape May. We strive to fulfill our mission of empowering gastroenterologists to deliver compassionate, high-quality, and comprehensive care through an unparalleled patient experience. We offer treatment for many conditions and diseases such as Abdominal Pain, Barrett’s Esophagus, Celiac Disease, Inflammatory Bowel Disease, Crohn’s Disease and Ulcerative Colitis, and Liver Disease. Our board-certified GI doctors specialize in performing various GI procedures, including colonoscopy, esophageal dilation, flexible sigmoidoscopy, upper endoscopy, and small bowel enteroscopy.
Our practices utilize a state-of-the-art electronic medical records system, enabling us to be more responsive to our patients’ needs. Our mission is to give our patients the most professional care possible.
You may notice some correspondence from our office with the name Allied Digestive Health. Allied Digestive Health was formed by a group of gastroenterology practices to provide quality care to all of our patients while adjusting to changes in health care delivery. You will continue to receive your gastroenterological care at the same location, delivered by the same physician. If you have specific questions about the name change and what it means to you, please discuss this with us during your next visit.
