The lieutenant graduated in 1999 from Bonny Eagle High School in Standish, and received a bachelor’s degree in 2005 from Tarleton State University, Killeen, Texas.

The six-week, in-resident course curriculum is designed to prepare the officer candidate for initial assignment as a commissioned officer and to serve as a foundation to build a career in the Air Force reserve components.

After graduation, the lieutenant either attends further career development training or returns to his or her resident state unit of assignment.
