Northern Light Mercy Surgery, formerly named Portland Surgical Associates, is made up of Maine’s most accomplished surgeons, who made the choice to create a highly specialized surgical practice focused on creating the best possible outcomes and patient experience. Our patients are seen as a whole person, not as an illness. Patients receive 24/7 access to dedicated, highly skilled, board-certified surgeons; a personalized treatment plan that utilizes the most advanced surgical techniques and non-surgical treatments; and private hospital rooms for recovery.

We offer surgeries and procedures for acute problems, including both simple and highly complex hernias, gallbladder disease, bowel obstruction, diverticulitis, and appendicitis. We also provide state of the art surgical treatment for cancers of the digestive system including colorectal cancer and esophageal cancer, as well as skin cancers such as melanoma. Our providers have extensive experience in minimally invasive techniques, which are employed whenever possible.

We also evaluate and treat leg pain due to varicose veins and venous insufficiency. Patients also get easy access to and seamless integration with interventional radiology, our Wound Care program, and hyperbaric oxygen therapy.
