Las Vegas Sands’ former president Michael Leven has retired from the company’s board of directors.

Leven has also retired from the board of its Macau subsidiary, Sands China. The company said in a filing that Leven had informed the firm on Monday that he had decided to retire from the board of directors of both firms, “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 filing to the Hong Kong Stock Exchange.

Leven, 77, joined the board of Las Vegas Sands in 2004. He was president and chief operating officer between 2009 and 2014, when he retired from those roles, remaining as a director. He was succeeded as group president and chief operating officer by Rob Goldstein.

In 2010 Leven was named acting chief executive of Sands China after the dismissal of Steve Jacobs. In July 2011 Edward Tracy was appointed to run the Sands China operation.

Leven was pivotal in Las Vegas Sands’ growth in Asia. During his tenure as president, the firm opened the Marina Bay Sands in Singapore and recorded huge profit growth in Macau, where it also increased its market presence.
