Dignity Health St. Joseph’s Hospital and Medical Center has selected Kristina Zimmermann, DNP, RN, as its chief nursing executive officer after an in-depth national search. 

St. Joseph’s President and CEO Gabrielle Finley-Hazle cited Zimmermann’s clinical expertise, executive leadership skills, and experience in strategic planning and daily hospital operations as major factors in her hiring.

Zimmermann previously served as vice president and chief nursing officer at John C. Lincoln Medical Center, which is part of HonorHealth.

At John C. Lincoln, she is credited with substantially improving the

hospital’s patient experience scores and increasing employee engagement. Other accomplishments include decreasing nursing turnover rates and eliminating agency labor through the development of a multidisciplinary float pool.

She has a Doctor of Nursing Practice from Old Dominion University; a master’s degree in nursing leadership, and a bachelor’s degree in nursing. She is currently working on a master’s degree in healthcare administration.

She replaces Tanya Osborne-McKenzie, DNP, MSN/MBA, RN, who had been serving as the interim chief nursing executive officer. Osborne-McKenzie will remain with St. Joseph’s as its new assistant chief nursing officer. She joined the St. Joseph’s team in October as senior director of neuroscience nursing. Prior to that, she served in several nursing leadership roles, including interim vice president of nursing and patient safety officer for Trinity Health – Saint Agnes Medical Center in Fresno, California.
