Both are tasked with leading the continued digitalisation of the office.
Choi reports to Lilian Leong, Hong Kong managing director, while Pang reports in Brian Ma, the agency’s deputy executive creative director.
Both new hires come armed with diverse digital experience.
Prior to joining Leo Burnett, Choi was head of digital marketing at ICLP, where he led the development of the mobile platform of Asia Miles. He developed and directed launch of an online entertainment platform at more than 15 service locations in Asia while with Billybala iGame Limited. During his time in MRM Worldwide Hong Kong, he designed and managed Intel's first ever award-winning Massively Multiplayer Online (MMO) marketing campaign.
"Digital is the means, not the ends," Choi said. "Our focus is to harness technologies and combine with creativity to transform the way people think, feel and behave."
Pang joins from Euro RSCG, where he drove the success of numerous social media campaigns for Carlsberg, Anna Sui, Pizza Hut and Hong Kong International Airport.
For example, in 2011 Pang helped Carlsberg kick off a digital campaign to crack the Da Vinci Code of rugby—beer and streaking—as part of the brand's official sponsorship of the Rugby Sevens tournament.
"It's my dream to work in an integrated agency that values big ideas above all else," Pang said. "Mainstreaming digital across the agency is an exciting task and experience."
Leong added, "The duo possesses an incredible amount of passion and vision. I look forward to seeing them scale new heights for our clients."
As reported last week, Leo Burnett and UM are tipped to win eBay classifieds sites' launch advertising account in Asia.
