As far as therapy programs in Oregon, I know there are a couple in the Bend/Redmond Area, which also brings up another point, the climate there is closer to Colorado, drier and colder. But there is LOTS of sun.
Second Nature is in Bend, OR
Sagewalk is in Redmond, OR
Catherine Freer is in Albany, OR.
There could be more, if you are a googlemaster.
Albany has the most easy access to boating; I mean the Santiam Drainage has multiple runs that go all year, Creekin', ocean is really close at Newport. Heck the Columbia Gorge is only 2 1/2 hours by freeway. And you have all the Coastal Mtn Drainages, Siletz.
Oregon State University is only 15 miles away and the University of Oregon is 40 miles to the South. So access to Co-eds can be a nice diversion, but you will be in the Willamette Valley home of 8 months of drizzle and fog.
