From Peramiho Abbey, the missionaries came to Kenya in 1971 with the invitation of His Grace, Most Rev. John Njenga, the then bishop of the Catholic Diocese of Eldoret.

He invited the missionaries to come and evangelize the Kerio Valley within his diocese. The bishop had personally visited Peramiho Abbey and met with Abbot Lambert Doerr OSB for this course. It was through the initiative of Peramiho Abbey, that the Conference of the General Chapter of the Benedictine congregation of Saint Ottilien dealt with a possible new foundation in Kenya. On 5th November 1971, the participants of the general chapter unanimously accepted the request of Peramiho Abbey to undertake the new missionary assignment in the diocese of Eldoret in Kenya. They officially started in 1972.

By chance, they also met His Eminence, Maurice Cardinal Otunga, the then archbishop of the Archdiocese of Nairobi who also asked them to start something within Nairobi too with special emphasis on Mathare Valley at Ruaraka. Luckily enough they met with someone who helped them get some space at Ruaraka.

They immediately founded the monastery at Ruaraka in 1978. They combined the apostolate in the parishes they founded in both dioceses and monastic life in the community. In 1979, the monastery was raised to the status of a Simple Priory. Then it was raised to the status of a Conventual Priory in 1988. Our Tigoni land was generously donated by His Eminence, Maurice Cardinal Otunga. The first construction of the monastery started in 1986. The church was consecrated in 1991 during the solemnity of the Epiphany by the same Cardinal.
