Curtis was born to Robert Wayne and Billie Hill in Huntsville, Alabama on May 20, 1954. He grew up in Huntsville and was involved in a variety of youth sports in Huntsville and Harvest. He graduated from Madison Academy in 1972, and there he met his high school sweetheart, Kaye Carmack. He and Kaye were married on May 31, 1975, and recently celebrated their 50th anniversary. Curtis loved playing football, basketball, and baseball for  Madison Academy. He graduated from the University of Alabama in Huntsville with a degree in chemical engineering. During and after college, he worked at GTE, as a materials engineer and manager. He went on to work for many years at KBM as the Vice President of Manufacturing. In 2012, he began a new phase of his career as a contracted engineer for NASA. He took much pride and joy in his multiple projects and collaborations with many universities and various NASA centers across the country. He was a subject matter expert for In Space Manufacturing and also involved in semiconductor research.

Curtis and Kaye had three children, Allison, Ashley, and Nathan. They all attended school at Madison Academy, where he served as a board member for 21 years.
