ATTENTION PATIENTS:

GIMEDRI has a goal to provide each patient with the care they need. However, due to the physician shortage in Rhode Island, and the number of patients in need of medical care – every appointment slot has become integral to meeting our goal.

Starting 10/03/2022 - GIMEDRI may cancel unconfirmed appointments to meet the healthcare needs of our community.

IF WE DO NOT RECEIVE A RETURNED CALL FROM YOU TWO (2) BUSINESS DAYS BEFORE YOUR PROCEDURE OR OFFICE VISIT, THIS IS CONSIDERED AN UNCONFIRMED APPOINTMENT, AND THE SPOTS WILL BECOME AVAILABLE FOR OTHER PATIENTS.   Please see our full policy by clicking here.

Welcome!

Gastrointestinal Medicine Associates

Welcome! At Gastrointestinal Medicine Associates we are pleased to welcome you to our practice. We believe that each patient and doctor become a team working together to treat an individual's digestive problems. Our Rhode Island gastroenterologists emphasize listening to better help in understanding your concerns and responding with the best treatment options for you. With the help of our professional staff, they also follow up to make sure that problems are resolved and your health improves.

We want our patients to be informed about their digestive problems and treatments, because informed patients make better decisions about their health and well-being. That is why we've included a section on this website covering common topics associated with gastroenterology and endoscopic procedures. We encourage you to look through these pages whenever you have an interest or concern related to your digestive health.

Our practice also knows that convenience is important to your selection of a gastroenterologist in Rhode Island. In these web pages you’ll find information about Gastrointestinal Medicine Associates' offices, including our locations, maps, directions, hours, and appointment scheduling. We have multiple office locations throughout the state allowing you easy access to our practice. Please feel free to contact us with any questions you have or to request an appointment. We hope you find our practice offers the accessibility and personal commitment you look for from a gastroenterologist.
