We live in the area.
I have heard excellent things about Charles Wright from alumni and parents. Our testing psychologist had good things to say about Bellevue Public and Seattle Country Day.
My only experience with Seabury is that my husband worked near the middle school campus and would see the students out and about a lot. He said they always seemed like nice kids.

I wish I had more information to share but I our son is only four so we haven't been looking too long.
