Ida Liu

As Citigroup undergoes a massive restructuring, Ida Liu, head of Citi Private Bank, is focused on the engagement and morale of a 3,000-employee team spread across 52 offices in 20 countries.

Liu's methods include traditional efforts such as frequent communication through emails and town halls and less conventional techniques that include inviting a nutritionist to advise on eating and a doctor to discuss sleep. She organized a competitive bake sale at the London branch and once invited a Buddhist monk to discuss guided meditation.
