He received his undergraduate degree and medical degree from the University of Virginia (UVA). After graduating from medical school, Dr. Gallahan completed his internship and residency in internal medicine at Duke University Medical Center. He completed his fellowship in gastroenterology at Wake Forest University Baptist Medical Center (WFU).
After completing his GI fellowship, he was selected to stay on at WFU to complete an additional year of specialty training in Advanced Endoscopy, with a primary focus on endoscopic ultrasound (EUS). He was fortunate to train with instructors who are nationally recognized experts in Advanced Endoscopy.
Because of his advanced training in endoscopic ultrasound, Dr. Gallahan has a special interest in diagnosing and staging GI cancers and managing pancreas diseases. He also cares for patients with a variety of GI disorders, including inflammatory bowel disease, acid reflux, swallowing disorders, liver disease, and biliary and gallbladder disorders.

“Taking care of patients is a great privilege and responsibility. I always try to be as thorough as possible, and my goal is to communicate openly and honestly with my patients. I believe patients will ultimately do better if they understand their illness and treatment plan.”
Dr. Gallahan grew up in the Northern Neck of Virginia. He attended Woodberry Forest School before his time in Charlottesville. Dr. Gallahan is married to a native Richmonder and has three children. He and his family regularly attend Hope Church.
Dr. Gallahan is a huge fan of all sports and avidly follows the Washington Commanders and UVA athletics. He enjoys coaching his children’s sports teams and likes to sneak away to the golf course whenever he can.
