Open Quote My daughter loved Griswold High, for the most part the staff was great. I did dislike the administration though; they did little to help my daughter and her friends when they had problems with other students and felt that there safety was threatened. They pick their favorite students and idolize them leaving the rest to defend themselves. The school security officer was a little strange, and I actually caught him snooping around my property one night (we live on a dead end street, surrounded by woods). He also tried pulling over a student on the highway once; he's a wannabe cop and made alot of the female students feel uncomfortable from what I heard. Other than that they have amazing musicals and many different courses for students. Close Quote
