After coming to faith in Christ from a Muslim background, Moumouni strongly felt called to a church planting ministry in the Muslim majority context of Niger in West Africa. The urgency of the calling led him to leave his teaching career and get involved with a pioneering church planting ministry in Niamey the capital city. In the pursuit of this God-given agenda he met his wife Shiona who was also involved in this pioneering ministry with a UK based mission (World Horizons).

They got married and went for a two years training at All Nations Christian College which concluded with diploma in Biblical and cross cultural studies. On their return to Niger in 2001 they worked with a multinational team to establish their first church, the Bethel church in the district of Dar-es-Salam. Later, they spearheaded another church planting initiative in a more deprived area of the city, the Penouel church in the district of Kwara-Tagui. This later venture has been cumulatively undertaken with a school building project to serve the surrounding community. Since the year 2010 they have been back in the UK but continue to serve the churches back in Niger in the quality of overseer and teacher to consolidate their roots and equip them for further growth and opportunities.

Currently Moumouni works with the Post Office. He has lately completed an M.A in Aspects and Implications of Biblical Interpretation (MAIAIBI) with the London School of Theology and Middlesex University. He and Shiona have two teenage children; Benjamin and Joash. As a family their hobbies range from walking, to cycling and canoeing. Moumouni is an ardent reader and have a keen interest on current affairs.
