Chan has been with OMD for over a decade.
Commenting on her appointment, Neil Stewart, Asia-Pacific CEO at Maxus, said "I am delighted that Caroline has decided to join Maxus as our managing director in Hong Kong. She is a fantastic talent who will really help drive the continued growth of Maxus and help our local and international clients with innovative and creative approaches to media. I look forward to her joining us in the near future."
Chan's departure follows that of Maggie Choi who resigned from her position as CEO Asia-Pacific after 13 years with the agency. Choi leaves the agency at the start of November.
Chan won 'media planner of the year' at the Agency of the Year awards in 2006 for her work for Levi's. She also clinched 'best media planner' at Hong Kong 4A's Media Awards for the same campaign that year.
