Collier, Mary

Mary Collier (she/her) has a deep love for the great state of PA (she literally has a keystone tattoo) and currently resides in Philadelphia. She started organizing in 2019 with the Sunrise Movement while earning her B.S. in Managing for Sustainability at Bucknell University. As a Sunriser, Mary won a local campaign to draft a climate crisis action plan for her city, led a 115-mile trek from Harrisburg to DC to push for the establishment of the American Climate Corps, was part of a team that helped secure Congresswoman Summer Lee’s 2022 victory by contacting over 3 million voters, and was very active in the coalition with PASU that won Whole-Home Repairs. When she’s not organizing, she enjoys going to concerts, cuddling with her cat, playing board games, singing karaoke, and sitting around campfires with friends and family.
