Megan Oldenburg, MSN, APRN, CNS

As a bedside nurse, one of the leaders I most admired was the CNS for our area.  She was an incredible mentor and still provides me with opportunities to ground myself and refocus on what inspires and drives the profession.  My main focus in pursuing a career as a CNS was to provide patients with consistent and appropriate care and to provide nursing with guidance on best practice.  Medicine is fascinating and I love to learn more every day.  My undergraduate degree was from College of St. Benedict and my graduate program was through Winona State.  As a CNS, I consider myself still fairly new in the role having just celebrated my 4 year mark in 2017.  I love working with other CNSs directly on a project, which often is not something I am able to do as we all cover different areas.  The opportunity to work with other CNSs in any capacity would be exciting for me and a great development and learning opportunity.  When not at work, I am spending time with my husband and three children under the age of 4.
