I retired from the Army after 27 years of service in the field of logistics. I served in a variety of locations including Iraq and Afghanistan. I have always wanted to teach and stay connected with the military. JROTC has allowed me to do just that. I have been teaching at Roosevelt High School since 2014 and I consider it an honor to mentor the next generations. In addition to teaching students about college and the workforce, I also teach character and discipline. These are tools students can use beyond college or the workforce.

I currently coach the award winning Riderette Drill Team and assists the other instructors with the many other co-curricular teams the Roughrider JROTC program has to offer.

If you have any questions please don't hesitate to call me!
