Loma Linda University Health Board of Trustees has voted on new administrators for Loma Linda University Children’s Hospital and Loma Linda University Medical Center – Murrieta. Peter Baker will assume the role of senior vice president and administrator of Children’s Hospital, and Jonathan Jean-Marie will assume the role of senior vice president and administrator for Murrieta.

“I look forward to an exciting future as Peter and Jonathan bring their talents to their new roles leading the Children’s Hospital and Murrieta teams,” said Kerry Heinrich, CEO of Loma Linda University Health hospitals. “While working with Peter over the years, I appreciate his leadership skills and forward-looking strategic planning. Jonathan is a results-driven healthcare executive who I know will thrive in serving the Murrieta community.”

Baker, who has worked for Loma Linda University Health for more than seven years, most recently served as senior vice president and administrator of Loma Linda University Medical Center – Murrieta. He holds Doctor of Law and MBA degrees from Golden Gate University.

Under Baker’s leadership, Murrieta has enjoyed streamlined operational processes, improved employee engagement, and sustained service line growth. He played a vital role in the Murrieta campus’s COVID-19 response, leading that team through the most challenging situations.

“Every day, Loma Linda University Children’s Hospital’s healthcare team meets the needs of our smallest, most vulnerable patients and their families,” Baker said. “Because we are able to join our commitment to whole-person care with the most advanced technology available, Loma Linda University Children’s Hospital’s approach is a model for the future of healthcare.”

Jean-Marie has served as vice president and administrator for Loma Linda University East Campus and Surgical Hospital since 2016. He has a master’s degree in healthcare administration from Florida A&M University.

During his tenure, both facilities received numerous awards for patient safety and excellence. East Campus Hospital received five consecutive Hospital Safety Grade “A” awards and was twice named a Top Teaching Hospital by Leapfrog. 

“I am honored to join the Murrieta team,” Jean-Marie said. “Much has been accomplished to improve the health and lives of Murrieta community residents. My goal is to strengthen and expand the amazing work that happens there every day. I am committed to working with our teams, our physicians, and community leaders to provide exceptional, patient-focused care to every resident in the region.”

Heinrich said the administrators are committed to ensuring a smooth transition and thanked both Children’s Hospital and Murrieta teams for their patience throughout this process.
