Although Caleb works with all medical cases, he has a particular interest in HIV and HIV related illnesses. He established a publishing company, Botshelo Publishing, in 2003, as his own consultancy venture, producing HIV and AIDS related publications for various audiences. ‘Botshelo’ is a Setswana word for ‘wellbeing’. He has also written two fiction books (published by Macmillan Botswana), and two nonfiction/ reference books of his own on the subject.

His two fictional books deal with the subjects of stigma, the importance of voluntary testing and the need for behavioural change. ‘Lethal Virus’ is about a young man whose risky lifestyle leads to him contracting the disease, while the second book, ‘A Deadly Twist of Fate’ concerns an innocent young girl who contracts the disease through a tainted blood transfusion. 

The two non-fiction reference books centre around HIV and AIDS, as well as human reproductive biology, with the aim to provide relevant life-skills information and AIDS awareness in schools.

Currently, he is working on a political thriller that is set against the backdrop of the land reform exercise in Zimbabwe.

When asked about the time he spent at UWCSEA, Caleb had this to say: “My fondest memories are of the camaraderie among peers from other cultures and races within the IB programme at UWCSEA. Although it is infrequent, I still maintain contact with a small circle of friends from that time, and having met several of them in the years since leaving, I am always pleasantly surprised that the ‘old’ rapport is quickly re-established – a sure sign of solid friendship. In academic terms, the tough IB programme left me unafraid of challenges demanding intellectual input, and I found the ‘Theory of Knowledge’ tutorials particularly beneficial.

"The community service with underprivileged and handicapped children at Tampines in Singapore, and my exposure to other cultures during visits to other countries in the region, including the Philippines, Malaysia, Thailand and Pakistan were also a memorable part of my time at UWC. The international experience that prevails at UWCSEA has expanded my insight into a wide range of social, political and cultural events that occur within Africa and beyond.”

Caleb is a member of the Botswana Chapter of the Southern Africa HIV Clinicians Society. At present he is a participant in the Public-Private Partnership in Botswana for the Anti-Retroviral (ARV) rollout programme. The programme provides medical care, treatment and follow-up services for the citizens of the country who require ARV treatment.

He is married to Norah, and has two children, 8 and 10 years old. Because of his own involvement in the IB experience, they sought, and were fortunate to find, a local school which has recently gained IB accreditation and his two children are now participating in the IBO’s Primary Years Programme with the ultimate aim of the IB Diploma. He says that it was a ‘heartening experience’ for him to hear the words ‘international understanding’ again in the setting of Botswana.

Caleb currently divides his time between his publishing/writing pursuits, his medical practice and his family. He looks forward to one day writing a chronicle of the two years that he spent as a youth in Southeast Asia.
