Inside Social Games can confirm that former Omgpop chief revenue officer Wilson Kriegel has left his position at Zynga.

Kriegel joined Zynga back in March when the social gaming giant acquired Omgpop for $180 million. The company is the developer behind the hit mobile title Draw Something.

Today’s news is the latest in a growing list of high profile departures from Zynga’s ranks. In early August John Schappert left his role as Zynga’s COO and his position on the company’s board of directors. In late August we learned that chief creative officer Mike Verdu had left Zynga to form his own company, likely with the blessings of  Zynga CEO and founder Mark Pincus, who will be an investor. Shortly thereafter, vice president of studios Bill Mooney and vice president of marketing Brian Britwistle announced that they would be leaving their positions at social gaming company as well. Finally, on Sept. 10 Allan Leinwand, who served as the developer’s CTO of infrastructure left Zynga to join ServiceNow as its VP and CTO.

Kriegel is still scheduled to speak at our Inside Social Apps 2012 conference as part of the Monetizing Social and Mobile Games panel.
