Dr Ahmed Kalebi (pictured), founder and chief executive of Lancet Group of Laboratories in East Africa is one of the few happy businessmen in today’s economy. When the Covid-19 pandemic is forcing many businesses to crumble, Lancet is doing well for itself. It is among the labs accredited with testing for coronavirus. The Pathologists Lancet Kenya started operations in 2009 as a single reference laboratory in Nairobi and over the years, grown into 35 branch laboratories and service points across the country. With over 25 subsidiary lab companies in Uganda, 10 in Tanzania and two in Rwanda, it is one of the largest independent laboratory service provider in the region. For Dr Kalebi though, the journey to the top began in Kibera slums from where he drew some of his most enduring business lessons.
