Our Staff

Our specialists in poison information are experienced nurses and pharmacists with backgrounds in mother-child care, emergency, critical care, as well as intensive care. Many of our specialists have completed a certification program created by the American Association of Poison Control Centers.

Our center has 16 board-certified medical toxicologists and 4 toxicology fellows who provide medical backup to the call center staff.

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®.
