Margo writes from her home in northwestern Montana. Her newspaper career began at age 20 at one of Montana's oldest weeklies. For nearly two decades, she continued in a fulfilling career of publishing award-winning community newspapers. After selling the enterprise, she began researching stories that deserved a wider audience. Her four children were grown which allowed time for research and writing. Mowbray paused just long enough to serve a term in Montana's state Senate.
Her creative biography, An Answering Flame – Journal of a Horseback Nurse-Midwife, won the 2014 Media Award from the American College of Nurse-Midwives.
Havoc Red – Surviving the Alaska-Siberia Route 1943 reveals an untold story of World War II.
Mowbray serves on her local hospital board and is a private pilot with over twelve hundred left-seat hours.
