At the age of 65 she felt God was calling for her to start a school for vulnerable children in an impoverished neighbourhood. After much prayer and asking after God’s guidance the call became so strong that she eventually believed God was serious about her helping in this way. So without the means to start this school but armed with faith she moved into a single rented room in Ng’ombe in July, 2003 from Roma where she was living at the time. By faith she started a Sunday school. Very soon children started coming everyday. So on September 1st 2003. She began what she called a nursery school with two children aged 5 and 7 years. Very soon the school went up to 9 children. By January 2004 the number had grown to 40 children. In April 2004 she began to recruit grade 12 untrained teachers whom she trained an hour before the children arrived for school every morning. It was still basically a Sunday school. With the help of Ng’ombe Basic School education material, the syllabus for a primary school was established. The school was registered first with the community school secretariat under the late Professor Kelly. The Secretariat sadly closed after two years and so Hope and Faith School was re-registered with the Registrar of Societies.  

The school was streamlined to start with three year old children in the  nursery school, five year old at Pre-school and six and seven years starting grade one. Three grade 12 untrained teachers were recruited. Soon the number went to five, then seven teachers. Mrs. Mumbi Conducted in-service training with help from the Ministry of Education teacher trainers during the school holidays. The teachers professional development began seriously in 2006 with the help of the Friends of Hope and Faith at Cumnor Church Oxford. Almost all the teachers registered themselves with teacher training colleges either certificate, diploma or degree correspondence courses. Currently three teachers have finished their first degree, seven finished their diploma courses and the rest have their teacher certificates. The school now does not have untrained teachers. As a result of this achievement the school’s progression was evident. The school quickly grew from just a junior primary school to one that could offer senior secondary education by 2013. The other thing that helped the school to grow so quickly were two aspects, the vibrant feeding programme financed by the Friends of Hope and Faith at Skye in Scotland, the Oxford friends and Miracle Family Church helped to keep a healthy school and also grew the confidence of the community In the school. The other encouragement was the scholarship programmes that paid fees for the many orphans by the Skye friends and Zambia Orphan Aid. The scholarships also were extended to tertiary for those determined orphans that got a certificate in their grade 12 examination.
