Thasunda Brown Duckett

A year and a half after taking over TIAA—with its nearly $1.2 trillion in assets under management—Duckett has steered the investment firm to record-high operating margins. She’s realigned the business to further focus on services that maximize retirement income for clients. Another top priority: continuing the work on financial inclusion that she pioneered as an exec at JPMorgan through efforts to reduce racial and gender gaps in lifetime savings.
