Hello! It is my privilege to lead Rimrock Jr-Sr High School as Principal. I assumed responsibilities as Principal in 2023 after teaching High School science for 2 years at Rimrock. Before that, I served as an active duty Air Force officer for approximately 12 years until transitioning into the Air Force reserves and starting a civilian career in education. I chose to enter into education because, during the course of my military career, I realized the importance of developing character, wisdom, and grit in our youth in order to equip them to be productive citizens and leaders for our communities and nation. I hope that, as Rimrock’s principal, I can facilitate a high-quality education for our students that prepares them for future success after they graduate.
My educational background is varied, as I graduated high school from a Illinois Math & Science Academy before attending the US Air Force Academy, where I received a degree in political science and foreign area studies. I also have a Master’s Degree in National Security Studies from the American Military University, and attended language schools at the Defense Language Institute as well as overseas in Russia and Oman. I am currently enrolled in the Educational Specialist program for Educational Leadership at Northwest Nazarene University.
During my time in the military, I held a variety of assignments in law enforcement, intelligence, and counterterrorism, both in the US and overseas. I’ve also been an instructor for leadership, character development, and process improvement, and worked with Congress and the Department of Defense in the Pentagon on violence prevention and resiliency for the Department of the Air Force. I have held command (leadership) assignments in Afghanistan and the United Arab Emirates overseas, as well as Nebraska, Nevada, and here in Idaho at Mountain Home AFB.
