Important DHI Events Update (as of 3/11/20)
After much review, dialogue with key stakeholders, and considerable evaluation of the evolving COVID-19 situation, we have made the difficult decision to postpone the DHI Management Summit in Austin, TX, originally scheduled for March 25-27.

Spring Technical School Status Update (as of 3/20/20)
Due to the ongoing public health situation surrounding COVID-19, we are confirming the cancellation of the DHI Spring Technical School in Lansdowne, VA, originally scheduled for April 19-26. Any new dates for upcoming schools this year will be announced as soon as possible to support your planning.

DHI Advocacy Center
Top of mind for many members are the growing number of state and local “shelter in place” orders and whether DHI members are designated as providing “essential services,” allowing for limited but continued operations. We are providing resources to our industry to communicate to their states.
