He graduated from Newcastle High School in 1962. He went on to join the National Guard, completing his basic combat training with honors at Fort Leonard Wood, Missouri. He was selected by the company commander as the outstanding trainee of Company C, 3d Battalion. He went on to Oregon State University pursuing a degree in civil engineering and later took classes at Casper College. He then started working with his dad at Pioneer Construction building pipelines. When his dad sold the business, he went to work as a crane operator for several different companies. In 1972, Dave purchased Wyoming Alignment where he worked on tire alignments and built trailers for the next few years. Eventually he went to work for Butte Pipeline and later transferred to Shell Oil which allowed him to use his experience and skills to build his career as an engineer.
