Dean Nitin Nohria, along with MBA & Doctoral Programs Executive Director Jana Kierstead, Professor Jan Rivkin, and student co-presidents, welcomed the class of 2021—more than 900 new MBA students—to Harvard Business School, encouraging them to lean on each other and learn from each other. Students moved into residence halls, participated in their first case study, met faculty and section mates, and discovered the residential campus they will call home for the next two years.
