Our Staff

Our specialists in poison information are experienced nurses with backgrounds in mother-child care, emergency, critical care, as well as intensive care nursing. Many of our specialists have completed a certification program created by the American Association of Poison Control Centers. Our center also has six board-certified medical toxicologists on call 24-hours a day as additional medical backup.

The Oregon Poison Center staff uses their experience, training, an extensive library of medical toxicology literature, as well as computerized resources including: POISINDEX®, Tomes®, Tomes Plus® and Identidex®.
