Dear Patients and Friends:

It is with mixed emotions that I am announcing my retirement, at the end of June, 2025.  I have practiced Gastroenterology for over 35 years, having joined Atlantic Digestive Specialists in 2011.

I have been truly honored by patient loyalty over the years, with some patients having seen me for 25+ years.  While it is difficult ending patient relationships that have lasted decades, I have every confidence my fellow GI doctors and providers at Atlantic Digestive Specialists can competently treat you.  We have multiple providers available to assume your Gastroenterology care in both our Portsmouth and Somersworth offices, ensuring complete continuity of your care.

Providers of this practice cover several area hospitals and ambulatory surgical centers, enabling patient choice as far as the location of any future procedures you may need to be performed.

I wish all my patients good health and happiness both now and in the future.

I look forward to spending more time with my family and traveling.  I am blessed with good health at this time and plan to squeeze in an occasional triathlon to remain active!

Sincerely yours,

Marylyn V. Grondin, MD
