Here's what we know:
* Mr. Neck: Melinda's English teacher. He is described as being obsessed with the book "The Scarlet Letter."
* Mr. Freeman: Melinda's art teacher. He's the only teacher who genuinely seems to care about her and encourages her artistic expression.
* "The Hair Lady": This is how Melinda refers to her guidance counselor, who seems unhelpful and dismissive of her concerns.
The novel focuses on Melinda's internal struggles and her journey of self-discovery, so the teachers are presented more as symbolic figures representing the different attitudes and responses she encounters.
