House of Delegates

The voice of AAPG's affiliated societies

AAPG’s House of Delegates (HoD) is made up of representatives from affiliated societies and international regions throughout the world. They are selected by popular vote from within their respective regions and serve a three-year term.

HoD leaders disseminate information from AAPG to their respective society or region and assist in recruiting prospective AAPG members. The HoD is led by three officers.
