The stoplight is a good place to begin. At Sunset and Quarter Horse, beside Southern Hills Hospital, a traffic signal finally gave Alexis Mussi something very ordinary to celebrate: a more convenient way in and out. In a county presentation in April 2024, she thanked the people who had made it happen. The wait, she said, had lasted years.
Executive biographies tend to prefer larger objects. A new title. A construction budget. An appointment with a date attached. Yet the intersection earns its place in Mussi’s story. A person running a large institution also has to care about how the institution meets the street. The building may have an impressive entrance; somebody still has to turn into it.
By November 2025, Mussi had a new appointment of her own: chief executive officer of MountainView Hospital in Las Vegas. She had worked there before, in roles that brought her closer to the practical machinery of running the place. Returning as CEO gave her career a loop. To understand the return, it helps to follow the work that came between.
A city learned through its institutions
Mussi joined HCA Healthcare in 2008 at Sunrise Children’s Hospital, as director of physician and provider relations. Her route into executive leadership began with relationships. The job came before the broader operations responsibilities that would later define her career. It also placed her inside the Las Vegas network in which she would keep working.
Her education combined business and communications at Arizona State University with public administration at the University of Nevada, Las Vegas. Those subjects belong naturally beside an institutional career: organizations have budgets, people, rules and obligations to the places around them. Knowing the vocabulary of one part does not automatically settle the demands of another.
In May 2009, she and three coauthors completed a UNLV capstone evaluating HELP Las Vegas Genesis Apartments. Shauna Davis, Bristol Ellington and Jason LaMarr Wasden shared the byline. The forty-page project began in November 2008 and included recommendations about budget transparency and continued funding. Here was an early piece of work concerned with whether a local institution was doing what it was supposed to do, and how its workings could be better understood.
Before the corner office, the operating job
By November 2013, Mussi had been promoted to vice president of operations at MountainView. She had previously overseen a narrower group of departments there. The promotion widened her responsibilities, including food and nutrition alongside other operational areas. A title can fit on a business card even when the responsibilities require rather more paper.
The sequence matters. Her later return to MountainView would bring her back to an organization she had known from within. Earlier leadership there was part of her working history, with responsibilities attached to particular departments and teams. Familiarity, in this setting, came from holding jobs in the institution before being asked to lead the whole.
Southern Hills became the next chapter. Institutional biographies place her arrival as chief operating officer in 2016. That same year, she appeared among the graduates of Leadership Las Vegas. Her professional development was happening both inside an employer and among people drawn from the wider city. The city remained the common address.
A first, followed by the work
In May 2019, Mussi became Southern Hills’ first woman CEO. The promotion followed her time running operations, and the institutional first gave the appointment significance beyond a change in title. She was taking charge of an organization whose workings she already knew. The announcement combined that continuity with a new responsibility.
Her statement at the time looked toward continuing to work with employees and volunteers and expanding the organization. It was an agenda grounded in the place she had been helping to run. There is something useful about reading an appointment through its verbs. Working, continuing, expanding: each points beyond the photograph that usually accompanies the news.
Recognition followed. In 2021, VEGAS INC included her in its 40 Under 40. She was also a recipient of the Trauma Intervention Program’s Heroes With a Heart award. The honors sit alongside the appointments in her career. They give the milestones dates and names; the years between them were occupied by the responsibilities of the job.
Expansion has a long middle
By the time of her move to MountainView in 2025, Mussi’s Southern Hills tenure included $110.7 million in secured capital investments. Two new floors were among the projects associated with that period. A figure that large is easy to place in a headline. Getting from an approved investment to a usable building takes longer than the headline suggests.
Capital investments secured, reported at her November 2025 appointment.
A floor expansion opened in August 2024 after work that had started in July 2022. The added floor covered 35,000 square feet. Later that year, another completed construction project involved both new space and renovation of existing space. Expansion, in other words, meant more than adding an outline to a plan. The established building was part of the assignment.
The two-year span of the floor project is worth keeping in view. It overlaps an annual calendar of decisions, meetings and other commitments, rather than forming a neat interval in which an executive does just one thing. That is one reason the construction history belongs in a personal profile. It gives some scale to the time spent in a role, beyond the dates at either end of it.
These details put a different pace on the career. Appointments arrive on a particular day. Projects occupy stretches of time, with existing operations continuing around them. For an executive, both clocks run together. Mussi’s years at Southern Hills included the long middle between announcing a plan and being able to open its doors.
Management, with a chorus
There was also a much less solemn management exercise. For an eighties-themed leadership development event, Southern Hills managers, directors and senior leaders made a music video. Their starting point was Bon Jovi. Their assignment was to incorporate workplace values. The resulting parody, Livin’ on iCare, had a title fit for an unusually musical management meeting.
Mussi posted about writing and singing with the team, and reported that they won the division’s video challenge. Anyone who has sat through a leadership presentation can appreciate the effort involved in giving one a chorus. The anecdote adds a little noise to a biography otherwise full of titles, committees and construction.
It also makes the group visible. The video belonged to a team undertaking a shared assignment. Her public account gave the team the applause. Alongside the formal responsibilities, there was room for colleagues to make something deliberately playful together.
Twenty years, all in the frame
In 2024, Southern Hills celebrated its twentieth anniversary. Mussi joined colleagues and Clark County Commissioner Justin Jones for the occasion. The photograph has raised glasses, gold balloons and people standing close enough to fit. It is a useful companion to the executive portrait: more of the workplace gets into the frame.
Institutions accumulate anniversaries while the people inside them experience changing jobs, new colleagues and projects that take longer than expected. A celebration briefly gathers those different calendars into one room. In this photograph, the organization’s age becomes an occasion for the people working there to stand together.
Mussi has also written about the help colleagues gave her. In a public appreciation post, she described support she had received as a leader and thanked the people around her. The direction of the gratitude is worth noticing. People with authority still rely on the judgment, effort and generosity of others in the building.
The return has its own responsibilities
Her connections extended beyond Southern Hills. She served on the Nevada Hospital Association’s board and chaired a regional facilities advisory board. She was also a founding member of the Ronald McDonald House Red Shoe Society. These commitments place her among the civic and professional organizations that connect a Las Vegas career to the wider region.
When MountainView welcomed her back in November 2025, the organization emphasized her work with teams and workplace culture. HCA’s Far West Division likewise pointed to teamwork and operations. The welcome reached back to her earlier service at MountainView while introducing her in the new role. The career had moved forward without leaving its local geography behind.
A room of firsts
In January 2026, she joined United Way of Southern Nevada’s Women Who Went First panel. The other speakers included Jan Jones Blackhurst, Las Vegas’ first woman mayor, and Hollie Chadwick, Nevada’s first woman SWAT commander. Melisa Eichbauer of Findlay Automotive Group also joined the conversation. Mussi brought her experience as Southern Hills’ first woman CEO to a discussion with leaders from quite different kinds of workplaces.
At the event, she described beginning each morning with a Mission Moment to stay connected to her work. It is a small, repeatable practice beside the larger milestones. The panel gave the 2019 appointment a new setting: several years later, it was experience she could discuss with other women leading organizations.
MountainView marked its thirtieth anniversary in May 2026. Ten employees who had been there from the beginning gathered for a photograph. Mussi’s anniversary remarks gave colleagues the credit for the institution’s recognition. The institutional calendar had supplied another occasion to put people at the center of the picture.
“This distinction belongs to our physicians, nurses and colleagues”
Alexis Mussi, May 2026
For Mussi, returning to MountainView meant taking responsibility for a place with a history that included some of her own. Earlier experience supplied context; the CEO job brought a new remit. The work ahead would have its own projects, its own teams and its own ordinary complications. Somewhere in the story, there will probably be another detail as practical as a turning lane. Those details deserve a place beside the title on the door.
