Current Parents Tell us Why They Choose Riverstone For Their Children

I am continually impressed how every faculty member is always coming up with new and innovative ways to engage and teach my kids ideas and concepts that are relevant to them and the world.

The combination of an excellent IB education coupled with incredible outdoor experiences makes RIS a wonderfully unique gift for our kids. The small community allows them to excel personally while the school’s global perspective gives them the base to understand and grow as positive and knowledgeable contributors to worldly issues.

Outdoor program and leadership by example are outstanding. The school really helps kids learn how to balance themselves into whole, unique humans with many different ideas of what success looks like.
