Riverstone was a great environment for our son who really thrived in the small classroom setting, with a rigorous academic curriculum and with teachers who were truly mentors throughout his 8 years there. Riverstone is the best educational opportunity presented to students in Idaho and beyond. I have taught in public and private schools and so, as a former teacher and as a parent, I can say that Riverstone has its vision, mission and act together.
