Why do the janitors and office staff despise the AD so much? Everyone knows the administration is incompetent and ineffective. Declining competitiveness, graduation, and attendance is likely a leading indicator of trouble ahead.

I love this school! I have taught it Monarch, Fairview, Arapahoe Ridge, and now Centaurus. This is by far my favorite! I love the culture and climate. The students are hardworking and kind, and the admin is super supportive!
