Mohegan, the tribal gaming and entertainment company that owns Mohegan Sun, has appointed an interim chief operating officer to replace the current COO, Jody Madigan, who is resigning.

Joseph J. Hasson will serve as interim COO while continuing to serve as general manager of Mohegan Casino at Virgin Hotels Las Vegas, subject to regulatory approvals, Mohegan announced.

Mohegan, which gave no reason for Madigan’s resignation, said Hasson was “an obvious choice for the Management Board,” given his experience. Hasson previously served as COO of Station Casinos LLC and Red Rock Resorts Inc.

“Joseph J. Hasson’s deep understanding of the gaming and hospitality industry makes him exceptionally qualified to maintain our high service and operational excellence standards,” Ray Pineault, Mohegan’s president and chief executive, said in a statement.

Madigan, who was appointed Mohegan COO in 2021, has resigned effective Aug. 1, and is taking a leave of absence until then, according to Mohegan.
