I've worked for NASA as a Mission Support Scientist, the Houston Health Department as an Epidemilogist and more recently, a business owner teaching and inspiring the youth to become engineers.   I'm entering my second year here at Marshall High School and fifth overall in education. I have enjoyed watching my students learn as they prepare themselves to achieve in every field of endeavor.
