About Us

Re:wild Your Campus is leading a nationwide movement to transform campuses into vibrant, sustainable, and safe environments. We are on a mission to eliminate synthetic pesticides from all college campuses in the U.S. by 2030.

Our Roots

It started with a volleyball practice at UC Berkeley in 2017. Founders Mackenzie Feldman and Bridget Gustafson discovered the courts where they trained had been sprayed with Ranger Pro, a glyphosate-based herbicide linked to cancer and environmental harm.

Shocked, they asked the Athletics Fields Supervisor to end spraying around the courts, and offered that the team would pull weeds themselves.

Since that day, Bridget and Mackenzie have made lasting, institutional change. The campaign spread across campus, and now UC Berkeley manages 95% of their grounds, 1,171 acres, organically without the use of inorganic fertilizers, chemical pesticides, fungicides and herbicides.

They were inspired to expand the campaign in 2019 after Dewayne "Lee" Johnson, a groundskeeper who developed cancer from spraying the same chemical, sued Monsanto. Herbicides were finally getting the attention they deserved, and students started reaching out asking how they could start similar campaigns at their schools.

In 2022, Herbicide-Free Campus joined forces with Re:wild, rebranding as Re:wild Your Campus. With expanded reach and support, the movement spread coast to coast, empowering students and groundskeepers to transform their campuses into safe, resilient, and biodiverse spaces.

Today, Re:wild Your Campus is a growing community of students, staff, and advocates working alongside groundskeepers and administrators to restore soil health and biodiversity. We're eliminating pesticides and transforming campuses into safe, resilient spaces where both people and pollinators can thrive.
