About
How We Got Started
When we founded Grassroots Change in 2009, we were moved by the need to nurture authentic public health movements. We also recognized the growing threat of preemption to grassroots movements on issues such as nutrition, tobacco control, agriculture and gun violence.
What We Do
Grassroots Change empowers grassroots leaders. We connect grassroots leaders with the evidence, tools and training to advance grassroots health and safety movements.
Grassroots Movement Building
Grassroots Change provides leadership, evidence-based research and technical assistance to advance authentic and effective grassroots movements and counter state and federal preemption.

Preemption Watch helps grassroots advocates understand, track and counter preemption. We share tools, research, and case studies, based on decades of experience and real-world evidence, to help advocates further their goals. Our Preemption Watch newsletter, website, and interactive Preemption Map provide timely coverage of federal and state preemption threats.
