Elizabeth S. John, M.D., gastroenterology

Hackensack Meridian Mountainside Medical Group has announced that Elizabeth S. John, M.D., gastroenterologist, has joined the practice.

A fellowship trained gastroenterologist, Dr. John is passionate about her specialty. “I have always loved gastroenterology as our digestive system really does affect so much of what we do outside of how we digest our food,” Dr. John shares. “The mind-body-gut axis is crucial to understand as our gastrointestinal symptoms can affect our psyche, and alternatively be affected by our psyche. Additionally, disorders of the gastrointestinal tract can have serious implications if not diagnosed early, and as such, I am passionate about teasing out important details of my patients’ symptoms to diagnose, treat, and prevent early.”


Dr. John received her medical degree from University of Central Florida College of Medicine. She completed her residency in Internal Medicine at Rutgers Robert Wood Johnson Medical School in New Jersey before completing her gastroenterology at Methodist Dallas Medical Center in Texas.  Dr. John is experienced in research with over 25 publications in academic journals, and over 60 presentations at academic meetings.  She has received number of awards and distinctions from the American College of Gastroenterology, the American Gastroenterological Association, and including the “Top 25 GI Fellows to Know” distinction, the “Early Career Investigator” distinction, the “Radhika Srinivasan Gender-Based Research Award”, and the “Presidential Award."


“We are pleased to welcome Dr. John to Mountainside Medical Group,” says Tim O’Brien, chief executive officer. “Our commitment is to the community and by expanding our physician network, we are better equipped to provide the highest level of quality care to area residents.”


When not treating patients, Dr. John enjoys spending time with family and friends, enjoying the art of music, learning new languages, cooking, and baking, finding ways to promote wellness.


Dr. John will see patients at 170 Changebridge Road in Montville, NJ. Make an appointment online by visiting mountainsidemedicalgroup.com or call 973-884-3355. Virtual care and in-person visits are available.
