Moumouni came to faith in Christ from a Muslim background and he felt called to a church planting ministry in the Muslim majority context of Niger in West Africa. This calling led him to leave his teaching career and get involved with a pioneering church planting ministry in Niamey, the capital city, where he met his wife Shiona. Shiona was also involved with church planting in Niger, working with a UK based mission organisation.

After a period of training and church planting in Niger, Moumouni and Shiona moved back to the UK in 2010.

Moumouni works for the Post Office, alongside this he has recently completed an M.A with the London School of Theology and Middlesex University.

Moumouni and Shiona have two teenage children, Benjamin and Joash.  Moumouni is an ardent reader and has a keen interest on current affairs.
