The Mater Comprehensive Care Clinic (CCC) opened on October 2nd, 2006 to respond to the need for HIV/AIDS treatment and care for the residents in the areas surrounding The Mater Hospital. The CCC clinic is funded by PEPFAR (President’s Emergency Plan for AIDS Relief), a US Government initiative, to counteract the devastation of the HIV/AIDS pandemic.  All care and treatment provided in Mater CCC is free to patients. 

The Mater Hospital undertook to manage the clinic in cooperation with CRS (Catholic Relief Services) and now CHAK (Christian Health Association of Kenya) as a way to reach out to the impoverished and HIV/AIDS infected people in the area.  CHAK supervises the funding and administration of the clinic and provides ongoing professional development for the staff.  The clinic has a multidisciplinary team comprising a doctor, clinical officers, nurses, counsellors, pharmacists and a nutritionist, and along with support staff currently serves 2600 registered patients. In addition Mater CCC also operates a satellite clinic at the Makadara Sisters of Mercy Dispensary. CCC services are available there every Monday and Friday by Mater CCC staff.
