CHAT provides a holistic approach to benefit both people and the environment.

Within an underserved community, CHAT directs support to the entire community including men, women and youth. CHAT also recognizes the most vulnerable and at-risk members of a community as part of the underserved individuals they support. This often includes people who are HIV-positive, sex workers, LGBTQ2S+ and people with disabilities.

Approximately 80% of the inhabitants receiving CHAT's services live in under-served rural areas. In Samburu, Laikipia, Isiolo, Marsabit, Mara, Amboseli & Baringo the people are largely transient, semi-nomadic pastoralists from a number of ethnic groups, including Samburu/Maa,  Pokot, Turkana, Borana, Somali, Mukogodo.

Meanwhile, we encounter mainly the Bantu i.e the Kamba in Kitui; Merian & Tharaka cultures in their eponymous county. In Nakuru County, CHAT is primarily providing services to an area inhabited by the Nandi, originally pastoralists now cultivators of land, as have also become the Ogiek who were originally hunter gatherers in the Mau Forest; also there are Kikuyu who are Bantu. In Nyeri, the people are of the Kikuyu culture (Bantu). In Nairobi we are working in a suburban slum, Dagoretti; here there are a mixture of many cultures being reached.
