We are one with healthcare professionals across America. Having worked in hospitals since 1998, A3 founder and LSS master black belt expert Erin Zeringue inspires scaleable, sustainable change management and process improvement for hospitals and healthcare professionals of all sizes, across all silos, one leader at a time, one culture at a time. Whether training teams for widespread cultural transformation, engaging stakeholders from board room to bedside, or fixing specific, yet complex system challenges, A3 understands how to ignite rapid change for achieving the highest level of reliability. 

Our Story

Overwhelmed by the Institute of Medicine’s report “To Err is Human,” A3 Healthcare’ s founder and CEO Erin Zeringue, found herself in a graduate school classroom, wracking her brain for real solutions to healthcare’s widespread, systemic brokenness.  At the time, she was pursuing her masters degree in healthcare administration at University of Alabama at Birmingham and had just completed a masters in biochemistry. The IOM report’s shocking transparency ignited her passion to become a healthcare change agent. That moment led her to learn best practices from the aviation and manufacturing industries via GE’s Lean Six Sigma certification program, and later apply them to real time work in the southern-most trenches of our nation’s health systems. Following a successful career leading quality within a large health system, Zeringue and A3 Healthcare are now empowering healthcare teams nationwide to solve some of the most complex clinical and operational challenges – facing healthcare professionals today.
