Heather Tennyson, FNP| Gastroenterology | MedStar Health
About me
Heather Tennyson is a certified nurse practitioner specializing in gastroenterology at MedStar St. Mary's Hospital, where she first started working as a nursing technician while attending college. She earned her Associate of Science in Nursing degree from the College of Southern Maryland and became a registered nurse supporting the MedStar St. Mary’s Telemetry and Emergency Departments for seven years, followed by 10 years at a local surgery center. While working and raising her children, Heather received her Bachelor and Master of Science degrees in Nursing from University of Maryland Global Campus and Purdue Global University, respectively.
In addition to a wide variety of gastrointestinal illnesses, Heather has extensive interest in treating acute and chronic diseases including irritable bowel syndrome, gastroesophageal reflux disease, and functional gastrointestinal disorders. She is a member of the American Association of Nurse Practitioners and the American Gastroenterological Association.
Heather, a native of St. Mary’s County, lives in Tall Timbers, Maryland, with her partner, three children, and Shih Tzu. She enjoys spending time with her family, reading, and putting together jigsaw puzzles.
"Every patient and their family are different, with their own unique needs. My goal is to design an individual treatment plan to help every one of my patients achieve the best possible outcome."
