The bank confirmed to Fund Selector Asia that Chan has resigned, but said she has not yet left the firm. No further details were disclosed.
Chan joined the private bank in 2013.
Under the leadership of Chan, the firm hired six bankers and advisors in April 2014 to expand its private banking business in Hong Kong. Rothschild said at the time it planned to significantly grow its private banking business in Asia.
The group has been present in Hong Kong for 20 years. Its private banking business established a representative office in 1992 and obtained its full license as a branch office in 2012.
Edmond de Rothschild Group has 31 offices in 19 countries in Europe, Asia, Middle East and South America.
