GZTV Every great classroom moment has someone behind it who said yes. At Renaissance Middle School, that person was Thelesia Barksdale, the AVID teacher who opened her 6th, 7th, and 8th grade classes to award-winning international model and Fashion Executive Justyn Burgest Graham. Barksdale has since retired, and the day she made possible now lives on GZTV as a lasting tribute to her work with students.
