The art program with Mrs. Blair is by far one of the best experiences I have had thus far. No matter that level you may be starting at she will be able to help you improve. Their choir also seemed to be pretty strong as well. The Drama/ English teacher is amazing and very passionate about her work there. Many of the teachers who were there when I attended seemed to be very passionate about their jobs. They helped me and so many others grow into better students and people in general. The math department may not be the best but it really came down to the students not even bothering to listen or do any of the assignments.
