GREENSBORO, N.C. --- Ray Parrish is a very popular history teacher at Northwest Guilford High School.
He has been a social studies teacher for nearly 20 years and has really been making a difference in his students' lives.
In fact, he was even a student there!
But now, he needs prayers.
Parrish suffers from astrocytoma---it's a form of brain cancer.
Luckily, he has his students by his side, leading the charge to support him---and using Facebook to spread the word.
