William Seto

William (Will) Seto assumed the National Council’s newly established chief diversity officer role in May 2023 to lead efforts promoting diversity, equity, inclusion and belonging (DEIB) throughout all aspects of the organization. Through collaboration across the National Council, he identifies DEIB opportunities and priorities, and supports the organization’s redesign efforts and cultural transformation.

An experienced and proven leader of DEIB programs, Seto previously served as director of diversity, equity and inclusion at Open Society Foundations, where he implemented all aspects of its global DEI strategy and partnered with staff at all levels to help refine and institute inclusive workplace practices. He has also been a DEI consultant for clients including The Wellbeing Project, Con Edison and The After-School Corporation.
