mrs. obrien is one of my favorite teachers at whitman. i had her for math b and precalc, and i currently spend about 75% of my ab calc class wishing i was back in obrien's class...dont take advantage of her while you have her. Dont forget your textbook either.

Most def one of the best that WW has to offer. She seems really uptight, but once you break through her tough side, she is such a sweet heart, and a really good teacher. I miss her, she was one of my favorite HS teachers.

She is nice outside of class, but strict as (bleep) inside of it. She commands control and she gets it.

Its hard to say, she is a good teacher but she is rude and mean. Her tests are unfair and she hardly ever gives them back. You'll learn a lot though

She is really mean and rude, but is unfortuantly a very good teacher.... She'll never smile, insult your intelligence, and scare you, but you'll learn a lot.
