Isabel Rojas // Statewide Board Chair

University of Massachusetts, Amherst

Isabel is the Statewide Board Treasurer for MASSPIRG. She transferred to UMass Amherst in the fall of 2022 for her junior year and is studying Microbiology. She joined MASSPIRG as an intern for the New Voter’s Project and helped register students to vote and educate them about their voting options in the 2022 midterm elections. She is now the campaign coordinator for the Democracy campaign (previously known as the New Voter’s Project) and is excited to continue to work with the UMass community to get classes off for the next elections in 2024 and gather support for same-day voter registration in Massachusetts to present to legislators in a future lobby day. Outside of MASSPIRG and academics, Isabel enjoys reading, spending time with her dog, and painting with friends. After graduation, Isabel plans to attend medical school and apply what she has learned about advocacy and leadership to her practice of medicine.
