Daughter is now a Junior.Principal Wynne Satterwhite is outstanding - I seldom meet such a hard worker. I know she works long hours and has an amazing memory for many of her students!! Her counselors, teachers (e.g. Messner, Arias, Russo,Blach,Wei,Cathy) badminton coaches all deserve medals of honor!!Daughter started 2017. She liked all the teachers. Great facilities. All teachers I met seem dedicated and nice. I like their Challenge Day where kids are taught to be nice to fellow classmates. I'm glad I volunteered for the 3 days they brought pioneers/captains of different industries to educate kids about their professions and how they succeed in life and how to avoid bullying by appreciating fellow students, some of whom are hurting inside. I learned a lot from these lectures.
