He's retiring... but he was (is) a fantastic person. He really knows his history, but you don't really learn much....
GH is one of the teachers I still remember (and I graduated in '90!!). Take International Studies... the BEST! Makes you want to learn... I've got to get back to visit him!
You must take a class by GH, if not for the learning he can give you but for his quickrip and travel stories.
One of the very best teachers you will encounter. He sets his classes up to be as simple as possible, and his flexible teaching style makes junior year easier.
You MUST take a class with him! What he teaches is one of the few things in high school that is actually important and he teaches in a fun way.
GH is the best! Anyone who graduates without having a class taught by him is missing out.
