Grace Yeh is a director of her family businesses, Yeh Brothers Wood Works and Yeh Brothers Electronic Works, and an active figure on the social and philanthropic circuit. She has organised a number of high-profile fund-raising galas, including the Yellow Ribbon Fund Charity Gala 2019 and the Singapore Symphony Orchestra (SSO) Benefit Dinner that same year.

Yeh is also a committee member of the SSO Ladies’ League, which was formed in 1984 to raise funds for the SSO via charity dinners, fashion shows and walkathons, among other initiatives. The proceeds are used to acquire musical equipment and instruments.

Besides her charitable work, Yeh is known for her sense of style; she tends to gravitate towards classic rather than trendy looks. She is a fan of Swiss luxury fashion house Bally, as well as the intricate creations of Chinese designer Guo Pei. Yeh also enjoys playing the partnership card game, bridge.
