Welcome to Long Island Gastroenterology Specialists

Long Island Gastroenterology Specialists is committed to providing you with expert medical care in a warm and compassionate setting. Our state-of-the-art equipment and capable staff will ensure that your medical needs are met and that we are your choice for the treatment of your digestive issues.


We would like to thank Dr. Philip Moskowitz for his years of service at Long Island Gastroenterology Specialists. Dr. Moskowtiz will be retiring effective July 1st, 2018. His patients can be assured the same level of compassionate and quality care with the other doctors at LIGS as they had with Dr. Moskowitz.

At the same time, we are introducing the addition of two new gastroenterologists to our practice, Dr. Carly G. Barth and Dr. Jarred E. Marshak.

Please call our office if you have any questions or would like to make an appointment with any of our physicians.
