Very diverse, supporting, and academically sufficient high school.

Good school
2 9/6/2010
The faculty at this administration are absolutely horrendous. None of the employees seem to care at all for the students, and when asked for assistance, they give you a an attitude as if it wasn't their job to help others sucdeed, all they care about are their own paychecks, and in my opinion, nearly all of the staff and teachers are corrupt scum. This is a disgusting embarrassment of a high school, and the students DESERVE much more.
