We've done a number of conferences annually since 2000 and 2001.  This means we have alot of history with alot of organizers.  The best way to check our references would be to go to these organizations websites and contact them, asking them directly about us.  Some organizations with whom we have a nearly-decade-long relationship (as of this writing in late 2011) are:

NICHE of Iowa, the state Homeschool group...contact Kerry Northway

CHEF of Missouri, the state Homeschool group...contact Teresa May or Candy Summers

Great Homeschool Conferences of Cincinnati, and other cities...contact Brennan Dean

ACSI Christian School Conventions...SouthEast Region contact is Bill Wilson, SouthCentral Region contact is John Craig

There are also countless speakers with whom we have a years-long relationship, including:  Todd Wilson, Jim Weiss, Voddie Bauchamm, Doug Phillips, John Stonestreet, Shelley Noonan, Carol Barnier, Jeff Myers, Steve Demme, and Susan Wise Bauer.  I feel very certain that any and/or all of them would be happy to tell you of our work and our positive relationships that we foster.
