St. Peter’s Approach to General Surgery

For our General Surgery care team, providing comprehensive, high quality care means offering a wide range of procedures from a highly-trained set of surgeons, including the only board-certified colorectal surgeon in Montana.

Whatever the procedure, our team makes sure you’re fully prepared by scheduling appointments prior to surgery to perform certain tests, provide preoperative information and allow you to ask any questions you may have.
