Hill + Knowlton Strategies Singapore has lost digital practice lead Adrian Heng and executive director Monica Alsagoff (pictured).
Heng has already left the PR firm, while Alsagoff is currently serving notice. The agency's Singapore lead Baey Yam Keng confirmed the departures to Marketing.
Senior director Ng Chip Keng has been promoted to executive director and associate Sunitha Chalam was promoted to director role earlier this year.
Heng was head of the firms risk management, crisis, digital and technology practice as well as digital lead for H+K Strategies Southeast Asia.
When contacted by Marketing, Alsagoff said she has not confirmed plans for her next move. Heng joined the company in March 2010 and Alsagoff in May 2011 to lead the firm's luxury division.
Baey described the departures as "natural attrition".
"We are happy that our staff has done well while with us," Baey said.
