Catherine Campbell


Dip Applied Science (Nursing), RN, MACN
Member since 2021

Following 25 years working in the acute hospital setting, Catherine accepted a position in the community setting which saw her establish and participate in the successful cross-directorate School Youth Health Nurse (SYHN) pilot program.

Her advocacy role and managerial style were recognised in the Canberra Hospital Awards.
