Creative agency TBWA Hong Kong has appointed Mike Choy and William Chow as joint leaders of the agency’s creative department. Under the new structure, Choy has been elevated to Creative Partner, joining existing Creative Partner, Chow. Together, they will support TBWA HK General Manager, Ida Mak, by taking joint responsibility for the day-to-day leadership of the creative department and the development of TBWA’s “disruptive and famously culture-shaping ideas.”
Chow is a two-time Grand Effie winner. His work has also been recognised across major creative awards, including The One Show, Kam Fan, and AdFest. With more than two decades of experience, Chow has led work across Hong Kong and the wider Asia region for brands such as Standard Chartered, adidas, Visa, LG and Alipay.
Choy creates immersive brand worlds that connect digital and physical spaces. Over the past 17 years, he has delivered brand experiences for clients including Starbucks, Hennessey, Lee Jeans, Wrangler and Lexus.
Choy also leads Design by Disruption (DXD), TBWA’s design unit, where he heads a multi-disciplinary team of artists, designers, and makers dedicated to crafting solutions that connect technology, space and storytelling.
Both Creative Partners will report directly to John Koay, recently appointed as Omnicom Advertising Hong Kong’s Creative Chief Officer, to lead creative and champion new opportunities for clients across the agency group.
“William brings sharp thinking and real clarity to the work, with a strong feel for the stories that genuinely connect,” said John Koay.
“Mike’s strength is creating these amazing brand experiences – blending creative instinct with deep tech understanding. Together, they represent a bright and balanced future for TBWA HK it’s going to be fun to be a part of.”
Chow, added, “I’m incredibly excited to be stepping into this role alongside Mike. We’ve always shared a belief that the best ideas sit at the intersection of strategy, storytelling and craft. This partnership allows us to collaborate more closely, push each other and our talented teams to innovate further, and ultimately deliver more meaningful and effective work for our clients.”
Choy, said, “This new structure gives us the opportunity to push Disruption at TBWA Hong Kong to another level. We are excited about the new possibilities from being part of the Omnicom Advertising family and believe with our new structure and capabilities we are strengthened as a comprehensive and future-facing creative partner for brands.”
