Oncology specialist Peter Wagner, MD, is a member of the Kalispell Regional Medical Center medical staff and the practice of Northwest Oncology & Hematology. He conducted his medical studies at Szent-Gyorgyi Albert Medical University in Szeged, Hungary, and completed his residency in internal medicine at Prince George’s Hospital Center in Cheverly, Maryland. Dr. Wagner then served as a postdoctoral research fellow in the Breast Medical Oncology Department at M.D. Anderson Cancer Center in Houston, Texas. Later, he completed a fellowship in medical oncology at Ochsner Clinic Foundation Hospital in New Orleans, Louisiana, serving during the time Hurricane Katrina hit that coastal region. Before heading for the Flathead Valley, he was a medical oncologist at High Plains Oncology in Pueblo, Colorado. Dr. Wagner treats patients with a wide variety of cancer diagnoses, and has a deep understanding of the emotional toll that the disease can take on all affected. He gained a great deal of experience working with patients under stress in the Hurricane Katrina aftermath, when he found himself with nearly 20 cancer patients who could not leave the hospital for quite some time. Not only were they dealing with the stress of cancer, but the fears and anxiety caused by the natural disaster. “That experience taught me a lot about people and how they handle stress,” he said. “I had to make a lot of tough decisions under very tough circumstances. In the end I learned that life’s stresses can bring out the best in some people.” In his free time, Dr. Wagner is a dedicated skier and mountain biker who is eager to explore Flathead Valley trails.
