Greg Lapp, MD, FRCSC, specializes in Ear, Nose and Throat (ENT) and Otolaryngology at Altru Professional Center and Altru’s Clinic in Devils Lake. He is passionate about providing exceptional care and enjoys the pediatric aspect of ENT. He is also proud that Altru ENT was the first in the state to offer Minimally Invasive Parathyroidectomy, an endoscopic surgery for patients with primary hypothyroidism. When he is not seeing patients, Dr. Lapp can be found outdoors or exercising. He enjoys windsurfing at the lake in the summer and downhill skiing in Montana in the winter.

Philosophy Of Medicine

“I treat patients as I want to be treated, and make recommendations as if they were a member of my own family. I like to answer questions for them that they have not thought to ask.”
