We have been watching COVID-19 closely because everyone’s safety is of the utmost priority to us. We are anticipating to have a hybrid event in May of 2021. This will include an in-person component and a virtual experience as well. As planning continues, we will monitor activities closely and if changes need to be made to this plan, we will post online and let those interested know via email.

This year’s conference is being held May 19-21, 2021 at the Kalahari Resort and Conference Center located in Sandusky, Ohio.
