Our Team

Our network is managed by a Secretariat that works in close coordination with a rotating Chair. Previously under the leadership of former Mayor Claudia Sheinbaum and now under Mayor Martí Batres, Mexico City advises the Secretariat as CHANGE Chair.

Shared Leadership

The Secretariat’s organizational model draws from a history of feminist movements that have demonstrated how shared leadership can inspire better decision-making, greater diversity of thought, increased effectiveness, healthier work-life balance, heightened creativity, and more risk-taking.
