Our Field Team

Led by co-founder and senior director Dominique Browning, Moms Clean Air Force is a national movement of more than 1,000,000 moms — and dads too! — who are protecting our children’s right to clean air — just as our parents fought for us, forty years ago, when the Clean Air Act was first passed. Learn more today.

Rallying that incredible force of moms and dads every day is our family of bloggers and grassroots field team, starting up state chapters to take our mission to local communities.

We are here to tell Washington: Listen to your moms. We share the air — and we want it clean.
