About the board

The Oregon Board of Licensed Dietitians oversees the practice of dietitians, who integrate and apply principles derived from the sciences of nutrition, biochemistry, food, management, physiology and behavioral and social sciences to achieve and maintain people's health through a number of approaches.

The Board of Licensed Dietitians consists of seven members appointed by the governor:

  • Two are members of the general public
  • One is a physician trained in clinical nutrition
  • Four are licensed dietitians who have been engaged in dietetic practice for a least five years

The term of office is four years, but a member serves at the pleasure of the governor. If a person serves two consecutive terms, a period of at least four years must elapse before the person is again eligible for appointment.
