 New to Jrotc

I have served at many levels and unit assignments throughout my military career with a focus to improve and make each one better than before. I have always worked to enable those I have been honored to teach and mentor to achieve more. My formal military training as an Explosive Ordnance Disposal Officer has exposed me to many training techniques and courses. As a secondary mission I have trained numerous soldiers and personnel on basic explosive safety and other hazards associated with the numerous contingency and combat operations being conducted. I have experienced training US, NATO members, Eastern European, Iraqi personnel, all who have their own unique cultural background styles. The biggest pleasure that I have attained though is teaching the future of this great country
