Sabrina Sideris, program director of CU-Â鶹¹ÙÍø's INVST Community Studies, takes great pride in working with CU students to help them learn to become engaged citizens and leaders. In fact, she was once one of those students. Sideris became interested in community-based learning and social justice when she was a CU-Â鶹¹ÙÍø undergraduate (1996-2000).
