ENPHO is governed by a General Assembly which comprises of 71 members from various technical and non-technical fields. The General Assembly makes the major decisions on policy issues and elects an Executive Board once every three years consisting of 11 members headed by the Chairman. The Board meets at least once every two months to monitor and guide the execution of various activities. The day-to-day operation of the organization is led by the Executive Director. The organizational structure consists of the following Units: Program Unit, Resource Center (RC), Environmental Analysis & Production Development (EAPD) Unit, Human Resource Development (HRD) Unit and Finance & Administration (F & A) Unit.
