Howdy from the Conference Committee Chairs !

It’s hard to believe that we are just seven months away from our 11th biennial international family conference. The conference will be held July 18-22, 2018 in Dallas Texas at the Embassy Suites DFW North.  Since rooms are filling up quickly, we have a added an additional block of rooms, we have a new childcare vendor, and the planning committee continues to work on the details to create a wonderful experience for everyone who attends.
