Mark Ranatza Named Chief Nursing Officer at Arkansas Children’s Northwest

Mark Ranatza, MHA, BSN, RN, will join Arkansas Children’s Northwest (ACNW) as chief nursing officer in March, concluding a national search.

Before accepting the position with Arkansas Children's, Ranatza served as assistant vice president of hospital operations at Manning Family Children's (formerly Children's Hospital New Orleans), where he played a key role in expanding behavioral health services, including leading the development of a 70,000-square-foot behavioral health canter.  

“Mark brings a wealth of experience in pediatric healthcare operations and a strong track record of driving innovation and improving patient care,” said Rustin Morse, MD, senior vice president and chief administrator of ACNW. “His leadership has been instrumental in improving patient experience and strengthening operations. We look forward to seeing his expertise and passion benefit ACNW.”

Ranatza has a diverse background spanning hematology-oncology, critical care, emergency services, and behavioral health. He earned a nursing degree at Louisiana State University (LSU) Health Sciences Center in Baton Rouge and a Master of Healthcare Administration at LSU Shreveport.

Ranatza succeeds ACNW CNO Michael Howard, who is pursuing another leadership role at ACNW.
