ADHA is structured on three levels:
ADHA’s 375 local dental hygiene associations are its component organizations that form the first line of involvement for individual members. The components implement community service programs and educational sessions and offer ideas and information about state and national policies.
As the state dental hygiene associations, the constituent organizations serve the components in their jurisdictions by informing them of national policies and programs, monitoring legislation and providing continuing education.
The national level represents the interests of all dental hygienists across the nation and provides educational and professional development programming. It consists of 12 geographic districts, each of which represents a group of constituents. The national organization receives input from the constituent and components through elected district trustees.
