Serve-a-Thon is an annual Y.E.S. volunteer event honoring Cesar Chavez Day and serving as the grand finale of the annual fundraiser.

For the past 56 years, Youth Educational Services (Y.E.S.) has empowered students to make a meaningful impact through volunteer programs that support local schools and community organizations. These student-led initiatives are thoughtfully designed to address community needs while fostering teamwork, leadership, and personal growth among student volunteers.

Through service projects that align with their passions, Y.E.S. student volunteers build a deep sense of belonging—both to Cal Poly Humboldt and the broader community—helping to shape their success in and beyond college.
