Sonida Senior Living Appoints Anton Nikodemus as
Chief Operating Officer
Veteran hospitality executive brings three decades of operational leadership to accelerate scalability, elevate resident experience, and
support ongoing growth
DALLAS, Texas – June 1, 2026, Sonida Senior Living, Inc. (“Sonida” or the “Company”)
(NYSE: SNDA), one of the largest, pure-play owner-operators and investors in U.S. senior living communities, announced today that Anton Nikodemus has been appointed to the newly created role of Chief Operating Officer (“COO”), effective
June 15, 2026.
Mr. Nikodemus brings 30 years of executive-level hospitality and operations leadership to Sonida, where he will oversee end-to-end operational performance across the portfolio. In this role, he will lead Sonida’s continued focus on elevating resident experience, scaling Sonida’s
operating platform, and driving continued margin expansion. Central to that work is SPIN (Sonida Performance Insight Navigator), the Company’s proprietary operating infrastructure that integrates resident care, workforce, and operational data
into a single real-time framework — enabling decentralized decision-making at the community level.
“Anton’s appointment reflects
Sonida’s conviction that operational excellence and exceptional resident care are the core pillars of operational success,” said President and CEO Brandon Ribar of Sonida Senior Living. “We are an operator-led company, and our competitive advantage centers on the quality of our local leadership and the infrastructure we build behind them. Anton has spent his career doing precisely this, driving margin
expansion, and operational efficiency inside dynamic organizations, driving results through disciplined, decentralized execution. His arrival as COO marks a meaningful step forward in our ability to grow earnings, scale our platform, and deliver for
our residents and shareholders.”
Nikodemus joins Sonida from NYSE-listed Seaport Entertainment Group, where he served as President, CEO, and
Chairman of the Board. In that role, he assembled a team of hospitality professionals, led the company’s spin-off from Howard Hughes Holdings Inc., and guided its listing on the New York Stock Exchange.
He oversaw a diverse portfolio of entertainment, hospitality and real estate assets in New York and Las Vegas, including the Seaport in Lower Manhattan, the Las Vegas Aviators Triple-A Minor Leage baseball
team, the Las Vegas Ballpark, a minority interest in Jean-Georges Restaurants and interests in air rights above Fashion Show Mall in Las Vegas.
Prior to
Seaport Entertainment, Nikodemus spent 18 years at NYSE-listed MGM Resorts International, where he held a series of increasingly senior leadership roles, culminating in his position as President and COO of CityCenter, overseeing the AAA Five Diamond
ARIA Resort & Casino, Vdara Hotel & Spa, and The Cosmopolitan of Las Vegas, including his oversight of the Cosmopolitan’s integration and accelerated financial performance following its acquisition. Earlier in his MGM tenure,
he served as President of MGM Resorts’ Las Vegas portfolio, leading more than 30,000 employees across properties including the Bellagio, MGM Grand, Mandalay Bay, and The Mirage, with combined revenues exceeding $6.8 billion annually. His
leadership spanned transformative periods including the MGM 2020 restructuring and the COVID-19 pandemic.
“I have spent my career inside organizations where the distance between strategy and execution is where value is won or lost,” said Nikodemus.
“What drew me to Sonida is that the foundation is already in place — the culture, the systems, the local leadership model. The Company is at an exciting inflection point where all of that starts to compound, and I could not be more
energized to help further scale this best-in-class platform.”
