Marla Dean is an extremely knowledgable educator, but as an administrator, she is completely ineffective. She rules like a dictator and is usually irrational, emotionally, and unbalanced in her decision making. Overall rude, condescending, evil!
I was one of her former students in '00-'01. She is a great person and teacher. I did not realize it then, but her teaching and daily reading helped me later.
She's a cool teacher and a cool friend. Just don't get on her bad side because you'll likely stay there.
