Outstanding Undergraduate Seniors
One student from each major in CALES, nominated by their department, is awarded a plaque and honored at a luncheon every semester. These are University of Arizona students who go above and beyond in their volunteer work, research and internships to make a difference on campus and in the local community.
To celebrate the hard work, dedication and achievements of our graduating seniors, we compiled interviews with ENVS and SPS Outstanding Seniors.
