AONL grieves the unexpected and devastating loss of Sammie Mosier, DHA, MA, BSN, NE-BC. A longtime AONL member, she offered her vision with steadfast dedication to nurse advocacy, colleague engagement, and the development of leaders at every stage in their career.
Dr. Mosier served as Senior Vice President and Chief Nurse Executive for HCA Healthcare. She transformed the national health system by spearheading advocacy initiatives to elevate nursing voices in policy, establishing a program to recognize unit-level excellence, and pioneering a residency program to advance early-career nurse development.
AONL will remember Dr. Mosier for her leadership defined by empathy and expertise. Her influence endures in the leaders she mentored, the nurses she championed, and the systems she helped shape.
Our thoughts are with her family, friends, colleagues and all who are experiencing the loss of a remarkable leader.
