Welcome to Green River Wyoming and Expedition Academy High School! As principal of Expedition Academy High School it has truly been a humbling and awesome experience in working with our students and staff. I have worked for Sweetwater County School District #2 for the past 5 years and in education over 20 years. I have taught English Language Arts, Science, Physical Education, and Health before becoming an administrator. My wife and I are both educators who love Wyoming and Green River.

I enjoy spending time with my family and enjoying the wonderful Wyoming outdoor activities such as hunting, skiing, fishing, camping, and hiking in the mountains.

Expedition Academy is a great place and we have AWESOME students! It’s a privilege daily to work with each of our students in trying to help them reach their goals. If you have questions or concerns, please reach out by phone, email, or call and set up a meeting time with me.
