The GCUOBA was founded to keep Old boys of the institution in touch with one another and to support the School as a united body. There are currently some 5 000 members worldwide. Umuahians are able to maintain or renew friendships either by logging on to a secure password protected website, GCUOBA Online, where names and contact details are listed.
As well as the List of Members, the Association also host an annual Homecoming, publishes a Magazine. There are regular e-bulletins too. If you are an old boy who is not on our mailing list for these publications but would like to receive them in the future, do please contact the GCUOBA or update your details here.
