To pay back a medical school scholarship, Dr. Karen Gedney was required to work four years in an underserved area, and she got assigned to the Northern Nevada Correctional Center back in the 80's. It's a medium security facility outside of Carson City. Gedney ended up staying her whole career. She says the job was a 'calling' that provided her the chance to be a real healer. Her new book, 30 Years Behind Bars, chronicles her experiences as a prison doc, and KUNR’s Holly Hutchings spoke with her about it.
