St. Peter the Fisherman Illeret parish is located at the eastern shore of Lake Turkana and at the border of Kenya and Ethiopia in the Catholic Diocese of Marsabit. It was an outstation of North Horr parish. Right Reverend Ambrose Ravasi, the then bishop of Marsabit had on a number of occasions requested the Benedictines to take up the challenge of bringing the Benedictine presence among the Daasanach people. In 2003, Fr. Florian went on a scouting mission assisted by the priests of North Horr parish who had embarked on plans to start mission work.
After thorough deliberations, the Benedictines took up the task and Saint Peter the Fisherman was officially opened on 29^th of June 2005 on the occasion of the solemnity of Saints Peter and Paul. Rev. Fr. Florian became the first parish priest where he served for about 16 years.
