The man who was pivotal in the growth of Las Vegas Sands in Asia has bade farewell—completely—to the company.

In a filing to the U.S. Securities and Exchange Commission on Tuesday, the Las Vegas-based casino operator announced that its former president, Michael Leven, has retired from the company’s board of directors.

Leven informed the company on Monday that he has decided to retire from the company’s board of directors and also from the board of its Macau subsidiary Sands China Ltd., “effective immediately.”

“Mr. Leven has decided to retire and has confirmed that he has no disagreement with the board, and there are no matters that need to be brought to the attention of the shareholders of the company in respect of his retirement,” Sands China said in a separate filing to the Hong Kong Stock Exchange.
