Department of Anesthesiology Featured Member: January 2026
Katie Myler, an Acute Care Nurse Practitioner, joined the Department of Anesthesiology in April 2022. She holds a Master of Science in Nursing from Saint Louis University, awarded in December 2021. Before embarking on her role as a Nurse Practitioner, Katie has accumulated valuable experience as a Cardiovascular ICU Nurse since 2016. This background inspired her to further her expertise in critical care and cardiac surgery. Currently, she serves in the Cardiothoracic Intensive Care Units at Barnes-Jewish Hospital and Missouri Baptist.
Katie was named the APP of the Quarter in Dec. 2025! Here is what her nominator has to say about her:
“Katie consistently demonstrates exceptional clinical expertise while also serving as a dedicated preceptor and mentor to new APPs and cross-trainees. She is highly regarded by CTI attendings for the knowledge she brings to rounds and her ability to teach complex concepts in a clear, supportive, and nonjudgmental way. Katie also contributes to our social and wellbeing committee and is always willing to lend a hand. Her positive attitude, professionalism, and commitment to others create a welcoming, high-performing team environment and truly reflect WashU values.”
Congratulations, Katie!
