Paul Greebie is Casey's laid-back guidance counselor. Casey's constantly goes to him for advice when she gets stressed, which is quite often. He doesn't do much. Although Casey has asked him, he won't tell her what to do; he will only give suggestions. Most of the time, Casey will ask him questions and then immediately answer them herself. He is also very clumsy. Once, when tipping his chair back too far, he fell and landed in the trash can. He is also very disorganized, and is also the computer/science teacher in addition to being Guidance Counselor.
