Katheryn Courville, RN PhD CEN

Katheryn teaches in the undergraduate and graduate nursing program at the University of Texas at Tyler in Longview.  She recently took a leave of absence from emergency nursing practice to focus on research and scholarship activities.  She has been a member of ETENA since 2005 and wants to grow the chapter’s influence in its communities by becoming the experts in emergency care.  She has experience in research, grant writing, presentations, and publications and she is willing to help anyone who has ideas for a research study or manuscript. Emergency Nurses know what we do, but the public doesn’t!  We must toot our own horns and be masters of our industry.  The way to do this…speak out and publish!
