Mok, who has been with Assembly since 2018, previously served as General Manager in Korea and has been instrumental to the agency's growth, playing a pivotal role in reimagining the agency's services to meet local market needs. Under her leadership, Assembly Korea has transformed from a performance-led agency to a data and tech-driven, omnichannel operation led by nearly 100 marketing professionals, delivering media, business consultancy, and more.

"North Asia is one of Assembly's most dynamic and strategically important regions," said Brosgill. "Vivian's vision and capacity to challenge the traditional agency model in this highly nuanced market has already made a lasting impact and will pave the way for more strategic client and business partnerships. We are thrilled to have her take on this new position".

As Assembly moves into 2025, the North Asia region will become an even more integral part of the company’s global strategy. Mok’s promotion is part of a broader initiative to invest in the business, attract top talent, and foster innovation for its global client portfolio, which includes WeWork, Moncler, Gentle Monster, and others.

"The North Asian market has been extremely resilient and has shown a promising shift over the past year as consumer confidence recovers," said Mok. "Our expansive global network and media expertise position us perfectly to help brands realize their local and international ambitions. I am excited to take on this new role".

Under Mok's leadership, Assembly's North Asia region aims to make significant progress in the market in the coming months, further strengthening its ability to drive the change that fuels growth for clients and brands. This appointment is effective immediately.
