    Black Student Alliance Conference

    The Black Student Alliance Conference is an annual effort to bring together collegiate and high school students to commemorate and celebrate the work of Black Student Unions in the Greater Rochester area. The event will serve to create unity and camaraderie amongst Black students while simultaneously acquainting high school students with college life. Students will work together in a variety of workshops to hone their leadership skills and build connections with the community. Our intention is to prepare Black students for organization and leadership responsibilities on a scale larger than individual schools.
