Mater Misericordiae Hospital was opened in 1962 by the Sisters of Mercy, a Catholic Order of Nuns originating from Ireland, three years after registering themselves as the Registered Trustees of an entity under the Perpetual Succession Act (the succeeding legislation after independence).
Between 1972 and 1986 the hospital expanded in various ways;
- Mater was chartered as a School of Midwifery.
- A consultant's block of 6 offices was opened enabling specialised consultants to practice on site and deliver significantly better medical skills to the patients.
- The Hospital opened its own pharmacy, physiotherapy and laboratory services
- Counselling centre for patient and staff commenced.
- A larger and more efficient Casualty, Accident and Emergency Department, an Intensive Care Unit and a Cardiac Unit where open-heart surgery is performed were opened.
The Hospital in accordance with the philosophy of the Sisters of Mercy aims to reach out to all members of the community irrespective of race, colour or creed, to continue the healing ministry of the church and preserve the heritage of the Sisters of Mercy.Mater Misericordiae Hospital is committed to be a leading healthcare provider in East and Central Africa and to benchmark itself against the highest attainable world standards, seeking continuous improvement.
