James Poe Castberg was born on July 12, 1933, in Powell, Wyoming, to William and Harriett (Jones) Castberg. Jim graduated from Powell High School in 1951. His first real job was working as a "Hod Carrier." Jim worked hard carrying bricks, stones, mortar, and other construction materials up and down ladders to the stonemasons and bricklayers..

Jim went on to attend the University of Wyoming with an interest in studying law. He was persuaded to get a Bachelor of Science Degree in Geology first. If practicing law did not work out, Jim would have a promising career to fall back on as a Geologist. Jim also joined the Reserve Officers' Training Corps (ROTC) on campus. Happily, during this time he also met his future bride, Jeanne Eleanor Northrup, and they were married on September 25, 1955..

After obtaining his degree in Geology, Jim began his four-year active duty with the Air Force which included flying many missions to Europe. Three years later, Jim and Jeanne welcomed the birth of their daughter, Ann, at Plattsburgh Air Force Base in upstate New York on November 27, 1958. After completing his active duty, Jim continued pursuing his dream of becoming a lawyer. He attended the University of Wyoming Law School for three years while beginning his Air Force Reserve career. After graduating from law school, Jim began a law practice in Powell, Wyoming, that would span nearly 60 amazing years..
