The Colorado Nanotechnology Association (CNA) and the Colorado Photonics Industry Association (CPIA) are moving from Denver to Boulder, the Boulder Economic Council announced at its first economic summit last week. Both associations will be located at the offices of Ehrhardt, Keefe, Steiner and Hottman, PC. The CNA and CPIA offices are currently housed in the Advance Colorado Center in the World Trade Center in downtown Denver. The council said the move will facilitate better collaboration for both groups, as most of their industry base is in Boulder, as well as the University of Colorado at Boulder, a frequent partner. The move is expected to be completed in late June.
