CHRISTUS Health announced today the appointment of Lillian Montoya as senior vice president for the New Mexico region, a newly created role that underscores the health system’s deep commitment to delivering exceptional, locally led care across the state.

Montoya will also continue in her current position as president and CEO of CHRISTUS St. Vincent Health System.

A native New Mexican, Montoya has been a part of the CHRISTUS Health ministry for more than 11 years, serving in progressive leadership roles since 2013 and becoming president and CEO of CHRISTUS St. Vincent in 2018. Her expanded role will include strategic oversight of CHRISTUS Health’s New Mexico efforts.

“Lillian Montoya is a purpose-driven leader who has delivered outstanding results and inspired transformation in every role she’s held,” said Ernie Sadau, CHRISTUS Health president and CEO. “Her expanded role positions us to unify and further the care we provide throughout New Mexico.”

Under Montoya’s leadership, CHRISTUS St. Vincent has become a recognized leader in health care excellence. It is the highest star-rated hospital in New Mexico, earning a four-star rating from the Centers for Medicare & Medicaid Services (CMS), and is the only hospital in the state to receive a Leapfrog Hospital Safety Grade of “A.” These accomplishments directly reflect CHRISTUS’ deep commitment to quality, safety and patient-centered care.

“I am deeply honored to step into this regional leadership role,” Montoya said. “I look forward to continuing our work in caring for the many—alongside our incredible caregivers and partners—ensuring that our communities receive the very best care, grounded in compassion and excellence.”
