I LOVE MILLENNIUM!! I originally didn't want to go here because I've heard a few bad things about this school, but I can vouch that I nor anyone else I know of has experienced anything of that sort from a counselor, administration, or their peers. Bullying is not an issue at this school either. Coming to this school has been one of the best experiences of my life! The people are great and so are the teachers. I'm a huge fan of their IB program and many of my friends speak fondly about their agricultural program. Everything about this school has been amazing for me and I feel like the counselors genuinely care about the students. The reason I gave four stars instead of five is because the campus is really crowded which can be annoying but it's not a deal breaker for me.
