I don't think there is anything like this camp in Portland. If you have a child who loves learning and is motivated then they will love the programs here.
Although they don't have a playground on site, they do spend time outside, take nature walks, excise etc.
Their classes are fantastic: math, geology, chemistry, ceramics, etc. All are designed to learn in a fun way.
The teachers are energetic, creative, and are experienced working with advanced learners.
They get a thumbs up from us!
Pros: fantastic focus classes, great educational materials
Cons: no playground onsite
