Castillo is an infectious diseases physician and medical director of Antimicrobial Stewardship at the University of Colorado Hospital in Aurora.. She is passionate about building collaborative, supportive relationships with clinicians and supporting them to optimally utilize antimicrobials in their daily practice.
How stewardship teams communicate determines whether interventions feel like policing or collaboration. Using structured, data-driven frameworks— advocacy-inquiry-listen-teach and DART—creates psychological safety to explore understanding and supports shared decision-making.
