Our team

Our Kids’s Climate operates under a shared co-directorship leadership model with Jill Kubit and Maya Mailer at the helm. We are a small team of movement, campaigns, and communications experts who passionately believe in the power of the parent voice and intergenerational solidarity to drive climate action.
