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, gun violence, and environmental justice. We’ve worked at the intersection of grassroots power and preemption by providing deep expertise on how grassroots leaders can overcome these obstacles to build effective movements for change.

What We Do
Grassroots Change empowers grassroots leaders to successfully build and sustain movements that improve health and safety at the community, state, and national levels.
How We Help You
We connect dedicated grassroots leaders with the training, research, and tools they need to advance their efforts on diverse public health issues, including food policy, agriculture, violence prevention, and sustainability. Through our e-communications and partner network, we share the latest news about successful movement strategies and threats such as preemption.
Grassroots Movement Building
Grassroots Change provides movement leaders with evidence-based research and technical assistance, as well as customized training to help advance authentic and effective movements and counter state and federal preemption.
