Our Team

Kim Barnas

CEO

Kim Barnas is the CEO of Catalysis in Appleton, Wisconsin. She actively teaches, mentors, and supports healthcare executive teams around the world. Her current focus is a principle-based approach to executive management. This system builds a new set of competencies (rooted in the Shingo model) in senior leadership teams who are looking to improve organizational performance. 

Prior to her role at Catalysis, Kim served as a senior vice president for ThedaCare and president of Appleton Medical Center and Theda Clark Medical Center. While in that role she enjoyed the opportunity to learn about operational excellence and implemented this work in hospital operations. The ThedaCare Improvement System (LEAN) path started in 2003, with value stream mapping followed by improvement events and projects.  She was involved in leading two of the initial value streams for OB and Cancer Services. 

As the journey continued, a new challenge emerged—the need for a systematic method to sustain improvement, clarify daily continuous improvement opportunities, and deliver on strategic deployment.  To meet this need, Kim and her team led the development of a management system designed to deliver improved performance through a predictable process that developed leaders, identified defects, solved problems, and developed people.  In 2014 Kim authored Beyond Heroes: A Lean Management System for Healthcare based on that journey. She also co-authored Becoming the Change: Leadership Behaviors Strategies for Continuous Improvement in Healthcare in 2021. 

Kim has a Master of Science in Health Care Administration.
