God called Didier into children's ministry, but he didn't know what children's ministry was until he started volunteering with missionaries Joel and Heidi Hayslip. He says, "God put a desire in my heart to go toward the people who don't speak my language when I started going on outreaches to unreached villages. Whenever there was an opportunity to go on an outreach, there was a great joy and excitement that would push me to go." Didier received his missionary call in 2012 when he went to the Turka people and saw incredible fruit.

Didier began volunteering with Children's ministry outreaches in 2004. He became part of the mission staff working with the Go To Nations Burkina Faso team in 2009. Two years later, he became the National Coordinator of CREE Ministry and in 2015, the Director of CREE Vision spreading the gospel to hundreds of thousands of children across Burkina Faso through evangelism outreaches that include puppet skits, songs, and drama. Didier continues to serve as an affiliate missionary with Go To Nations and has also founded his own ministry named MPJPAC/Enfants.
