About Us

 

Thank you for your interest in Atlantic Digestive Specialists

— Helping People Inside & Out —

The physicians and staff of Atlantic Digestive Specialists are committed to providing high-quality medical care to you, our patient. From our very first patient in 1973, when we were known as Gastroenterology Professional Association, we have put our patients first, taking the approach that both physical and emotional well-being are part of the equation to providing the highest care possible.

Our physicians are specialty trained, board-certified gastroenterologists with more than 100 years of combined experience caring for the digestive system. As the most experienced physicians with the most advanced diagnostic technology in seacoast New Hampshire, Atlantic Digestive Specialists are leaders in the field of Gastroenterology.

Working closely with you and your primary care physician, we address your gastrointestinal needs such as screening colonoscopy, as well as offering a full range of diagnostic services. We commonly treat patients with chronic acid reflux, peptic ulcer disease, Inflammatory Bowel Disease, chronic liver diseases, and all disorders of the digestive tract.

Our personalized approach doesn’t stop with diagnosis and treatment; it begins and continues with continuous patient communication and education. Knowing more about your problem, how to prevent it, how we treat it, and how to, in some cases, live as comfortably as possible with it, is our mission.

With two office locations and seven affiliated facilities, we are dedicated to making your appointment and procedure as convenient as possible without being put on a wait list.
