Council serves as the governing body of the College and fulfills specific roles and responsibilities as set out in the Health Professions Act.


Council's focus is to set organizational goals and directions for the College, which are implemented at the direction of the Registrar. Council governs on behalf of its owners and makes decisions in their best interest. Council members are all Albertans.

Council is comprised of 5 registered dental hygienists and 5 public members appointed by government. 

Councillors have no individual authority. Collectively, they are responsible for understanding the values, perspectives, wants and needs of the Alberta public and developing written policies within which the College and Council operates.
