Madigan will officially step down as COO on 1 August and will take a leave of absence prior to leaving Mohegan. He served in the role for more than two and a half years, having joined the business in August 2021.
Prior to this, Madigan worked in senior roles for various casinos and related business. These included Mohegan-owned Paragon Casino Resort, where he was general manager for over three years.
Hasson becomes interim COO while a permanent replacement is sought. He will also remain in his current role as general manager of Mohegan Casino at Virgin Hotels Las Vegas.
An experienced industry professional, Hasson was previously the COO of Station Casinos and Red Rock Resorts. He was also senior vice-president of operations at Station Casinos and the general manager of Graton Resort & Casino.
As interim COO Hasson will report to Mohegan CEO and president, Ray Pineault.
“Joseph’s deep understanding of the gaming and hospitality industry makes him exceptionally qualified to maintain our high service and operational excellence standards,” Pineault said.
“We are confident Joe’s extensive experience and proven leadership will ensure continuity in our operations and guest experience.”
More senior changes at Mohegan
The departure of Madigan is the latest change to the senior management team at Mohegan.
Last month, Mohegan also appointed Ari Glazer as its new chief financial officer, with effect from 1 May. He replaces Carol Anderson, whose departure was confirmed in October last year.
Glazer joins Mohegan after more than 20 years with investment bank Citigroup. Here, he most recently served as managing director and global head of gaming and hospitality client coverage.
Pineault is currently overseeing finance functions until Glazer joins at the start of May.
Both changes come on the back of a record 2023 for Mohegan, during which revenue hit an all-time high of $1.67bn (£1.34m/€1.56m).
Adjusted EBITDA hit $399.9m, the second highest in the history of Mohegan, just below the $403.9m record set in 2022.
