Our Team

Denver Health’s Department of Anesthesiology and Perioperative Medicine consists of a physician anesthesiologist (MD or DO) and a certified registered nurse anesthetist. As a leader in care throughout the region, we also use our expertise as a teaching hospital that is closely affiliated with the University of Colorado School of Medicine. All of our physician anesthesiologists serve as faculty at the medical school. To help train the next generation of health care providers, your care team may include an anesthesiology resident physician or a student registered nurse anesthetist.
