  • HPGD in Portland, GSA Connects 2021

    I hope that this correspondence finds you all well and safe.  I am looking forward to seeing some of you next week during the annual meeting.  Others of you will join us virtually.  This will certainly be different meeting than those past.  Please be patient with us as we try to navigate the new virtual world.

    Our division will have a presence at the meeting in Portland.  This year we have three sessions in addition to our luncheon and reception.  We will have our annual reception and book raffle---so clear those shelves! Below, you will find a list of events and locations.  If you are in Portland, do stop by the booth to say hello and catch up.
