DHI conNextions Shifting to Virtual Event
In light of the current environment and out of concern for the health and safety of all participants, AC Business Media—the owner of DHI conNextions—has made the difficult decision to cancel this year's in-person DHI conNextions event, originally scheduled for October 14-15 in New Orleans, in favor of a virtual event. The DHI conNextions virtual event will take place the week of October 19, one week later than original dates. Learn more about the virtual event and read the full announcement.

DHI Executive Leadership Transition
After a long career of dedicated service, the DHI Board of Governors announce the retirement of Jerry S. Heppes, Sr., CAE, Chief Executive Officer of DHI and the Door Security & Safety Foundation (DSSF), effective October 1, 2020. Read more.  

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.
