The Old Bo Boys Association (OBBA) has established chapters in various countries, including the United States, United Kingdom, Australia, and Sierra Leone. These chapters serve as local branches of the larger association, allowing alumni living in different regions to stay connected, participate in activities, and contribute to the OBA's mission.
Each chapter operates within the framework of the Old Bo Boys Association, aligning its activities with the broader mission of the organization. Through these chapters, the association aims to create a global network that transcends borders, uniting alumni from different parts of the world in a shared commitment to their alma mater and its values.
