On May 18, 2026, Mercy announced a significant leadership appointment that marks a new chapter in its approach to human resources. Mark "Mo" Moir has been named the Senior Vice President and Chief People Officer, tasked with overseeing the health system’s workforce strategy across multiple states. With a wealth of experience in executive human resources, Moir's new role emphasizes Mercy's commitment to attract, retain, and support its caregivers, ensuring they thrive in their professional environment.

A Leader with Rich Experience

Before this new appointment, Moir served as the Vice President of Talent at Mercy. His tenure there was marked by successful initiatives to enhance caregiver experience, showcasing his ability to build and maintain a strong workforce. Major stakeholders, including Mercy's President and CEO, Steve Mackin, praised his thoughtful and strategic leadership. Mackin stated, "Mo is a thoughtful, strategic leader who brings both creativity and clarity to complex challenges." His collaborative leadership style stands out as essential in addressing and advancing the health system’s priorities concerning its personnel.

Moir's background is noteworthy; prior to joining Mercy in 2021, he held the position of Enterprise Vice President of People and Culture at Centura Health. His experience also spans significant roles at Kaiser Permanente and Sanford Health, where he led transformative human resources strategies essential to large health systems.

With degrees including a bachelor’s, an MBA from the University of South Dakota, and a Ph.D. in leadership and organizational change from Antioch University, Moir is well-prepared to take on the complexities of his role.

Focus on Caregiver Support and Recruitment

In a rapidly evolving healthcare landscape, Mercy recognizes the need to prioritize its caregivers, focusing on hiring, recruiting, and retaining skilled professionals. Moir’s leadership will be pivotal in shaping the human resources team at Mercy to better serve healthcare providers. His objectives include enhancing compensation and benefits, promoting co-worker health, fostering a culture of inclusion, and improving overall organizational effectiveness.

Mackin highlighted the critical nature of Moir’s mission: "We have a special mission and culture at Mercy. Mo's top job will be to ensure our mission and culture engage the hearts and minds of all caregivers who call Mercy home." The goal is not only to strengthen the workforce but also to align personnel with the organization's overarching mission to improve patient care.

The Importance of Mercy in Healthcare

Mercy stands among the largest healthcare systems in the United States, serving millions with nationally recognized care. In 2025, Mercy provided over half a billion dollars in free care and community benefits, evidencing its dedication to serving the public even amidst the challenges in the healthcare sector. By establishing itself as the top large health system for patient experience, according to NRC Health, Mercy sets a high standard in healthcare services.

With Moir stepping into this leadership role, the health system is poised to bolster its workforce and, by extension, enhance patient care. By prioritizing the recruitment and support of caregivers, Mercy aims not only to improve its internal culture but also to solidify its status as the healthcare employer of choice.

In summary, Moir’s appointment comes at a crucial time as Mercy navigates the complexities of modern healthcare. His role is integral in continuing to advance Mercy's people priorities and fostering an organizational culture that values and engages all its caregivers, ultimately leading to better patient outcomes.
