• Stacey Kluttz, Principal Hello!  My name is Stacey Kluttz and I am proud to be the principal of Katherine G. Johnson STEM Academy. I am a native of Greenville,  and a proud GHS graduate.  I taught 4th grade for 11 years in Royse City ISD before coming back home.  I served as assistant principal at George Washington Carver Elementary for 3 years.   My passion in life is to be a light to those around me.  I am honored to serve alongside an amazing staff as we partner with our parents and community to prepare students for a world we have yet to know.
