Since joining HCA Healthcare in 2008 at Sunrise Children’s Hospital, Mussi has built a distinguished career rooted in operational excellence and patient-centered leadership. At Southern Hills, she oversaw the hospital’s expansion from 134 to 331 beds and led milestone projects such as the state’s first freestanding emergency room, ER at the Lakes, and the Division’s first psychiatric facility, The Pavilion. Under her leadership, Southern Hills expanded advanced specialties in gastroenterology, interventional neurology, thoracic and vascular surgery, and secured $110.7 million in capital investments for projects including two new inpatient floors, a Level III NICU, four additional operating rooms and two new freestanding emergency rooms.
Reflecting on her time at Southern Hills, Mussi shared:
“It has been an honor to serve alongside the incredible team at Southern Hills Hospital. Our patients, families and community have trusted us in their most vulnerable moments, and that culture of compassion and excellence will always stay with me. I am excited to begin this new chapter at MountainView and continue to build upon the legacy MountainView Hospital has already established in our community. My commitment to Southern Hills and our Far West Division remains strong—we are one team with one mission to advance patient care.”
Mussi, a graduate of HCA Healthcare’s Leadership Accelerator program, began her healthcare career at Sunrise Children’s Hospital in 2008, advancing through leadership roles that fueled her passion for operations and strategy. She led as Vice President of Surgical Services and Vice President of Operations at MountainView Hospital before joining Southern Hills Hospital in 2016 as Chief Operating Officer.
