Executive Director

Mackenzie graduated from UC Berkeley in Spring 2018 with a degree in Society and Environment and a minor in Food Systems.

Upon graduating in 2018, Mackenzie expanded the campaign to the rest of the UCs, and then nationwide, and Herbicide-Free Campus was born. The campaign resulted in the entire University of California system going glyphosate-free; HFC also worked with the Protect Our Keiki Coalition to get all herbicides banned from every public school in the state of Hawaii.
