I.D. Firms in CO for intern

As a Dutch Industrial design engineering student from Delft, currently studying for my masters, I would like to do an internship in the USA, particular in the Colorado area north of Denver (around Boulder, Ft. Collins).
At the moment I am orientating on Industrial Design firms in that area. Can anybody help me with listing interesting company’s over there?

I’m wondering what happened to the IDEO-office in boulder? (and to the designers working there? They still design don’t they? any new firms started or something?)
Also: does Volan design still exist? www.volan.com doesn’t seem to work.

Can someone share his/her experience with design firms in that area? Samson design for example? any advice?

Thanx in advance…
