Get to know General Surgeon Dr. Hermann P. Sigbjarnarson, who serves patients in New Hampshire.

Dr. Sigbjarnarson is a board-certified general surgeon whose area of focus is hernia surgery. He can be found on staff at Dartmouth-Hitchcock Medical Center & Valley Regional Hospital.

Dartmouth–Hitchcock Medical Center is the U.S. state of New Hampshire’s only academic medical center. It is headquartered in Lebanon, New Hampshire on a 225-acre campus in the heart of the Upper Connecticut River Valley. The mission of the medical center is to advance health through research, education, clinical practice and community partnerships, providing each person the best care, in the right place, at the right time, every time.

Valley Regional Hospital is a hospital located on 243 Elm Street in Claremont, New Hampshire, United States. It was established in 1893 as Cottage Hospital. As a 25-bed, 24/7-staffed emergency department hospital, it is the only such facility in Sullivan County. Its mission is to treat the community as family by providing quality, compassionate care.

Back in 2008, Dr. Sigbjarnarson graduated with his medical degree from the University of Iceland Faculty of Medicine. He then went on to perform his residency in general surgery at Dartmouth-Hitchcock Medical Center in 2015.

Licensed to practice medicine in New Hampshire and Vermont, the doctor is board-certified in general surgery by the American Board of Surgery (ABS). The ABS is an independent, non-profit organization located in Philadelphia, Pennsylvania, founded for the purpose of certifying surgeons who have met a defined standard of education, training, and knowledge.

Alongside his clinical role, Dr. Sigbjarnarson serves as an Assistant Professor of Surgery at the Geisel School of Medicine at Dartmouth.

General surgery is a surgical specialty that focuses on abdominal contents including the esophagus, stomach, small bowel, colon, liver, pancreas, gallbladder, appendix and bile ducts, and often the thyroid gland. A general surgeon performs a wide range of abdominal surgeries for many forms of intestinal and abdominal wall neoplasms, gallbladder disease, gastric and pancreatic disease. They follow the patient through critical care and surgical recovery all the way to outpatient care. 

On a more personal note, Dr. Sigbjarnarson speaks English and Icelandic.
