About:
I'm currently attending the University of North Dakota. I attended Spokane Falls Community College through Running Start as a junior and senior in high school and earned my Associate of Arts degree. I'll be receiving my bachelor's degree from UND in 2015, then after about one more year of flight training in Grand Forks, I'll be a commercial pilot. I'll be earning a Bachelor of Science degree in Aeronautics with a major in Commercial Aviation. I'm also planning on joining UND's Aerobatic Team.
