I went to GFS myself and have a 23 yr old who went to GSFS and then Masterman starting in 5th. I was not willing to send a kid to GFS. I can go into more specifics in DMs, but broadly speaking, GFS has not evolved socially since the 80s and is miserable when it comes to social emotional issues, and the academic rigor, while truly special, can also be found elsewhere. I'm also in the child development field and disagree with other posters that high school is more important than elementary. They're equally important, for different reasons. Private elementary can set your kids up to love learning and support their social emotional foundations, which they will have ingrained by the time they get to high school, when they need to become independent. It's only one kid, but when I tell you I never had to tell my child to do his homework one single time, I'm not exaggerating. I attribute that to his elementary / childhood learning experiences and being in a home where learning and curiosity were encouraged.
