Pope Francis has appointed Mons. Cleophas Oseso Tuka as the Bishop for the Catholic Diocese of Nakuru in Kenya and elevated the Apostolic Vicariate of Isiolo in the East African nation to a Diocese “with the same denomination and territorial configuration”.

The latest administrative change in Nakuru Diocese and the elevation of the Kenyan Vicariate was made public on Wednesday, February 15 by the Holy See Press Office and announced by the Apostolic Nuncio in Kenya, Archbishop Hubertus van Megen.

“I have the honor and pleasure to inform you that His Holiness Pope Francis has appointed the Reverend Father Cleophas Oseso Tuka, as Bishop of the Catholic Diocese of Nakuru. The Bishop-elect hails from the clergy of the Catholic Diocese of Nakuru,” Archbishop van Megen said in his statement to the members of the Kenya Conference of Catholic Bishops (KCCB).

Nakuru Diocese, which has been under the leadership of Bishop David Kamau as the Apostolic Administrator since 19 March 2022 became on 18 February 2022 when Archbishop Maurice Muhatia Makumba was appointed the Local Ordinary of Kenya’s Kisumu Archdiocese.

Until his appointment, Mons. Oseso has been serving as Vicar General and Parish Priest of St. Augustine’s Parish of Nakuru Diocese.


Born in November 1967 in the Diocese of Nakuru, the Bishop-elect was ordained a Priest for the same Diocese in June 1995 after his Priestly formation at St. Augustine's Mabanga Senior Seminary in Bungoma Diocese, and at St. Matthias Mulumba Tindinyo Senior Seminary in Eldoret Diocese.

He holds a Master's degree in Business Administration from Le Moyne College in the United States of America (U.S.) and a Doctorate in Education from the Graduate Theological Foundation in the U.S.

As a Priest, the Bishop-elect has served in various capacities, including Parish Vicar of Njoro; Parish Vicar of the Holy Cross; Diocesan procurator; Diocesan treasurer; and Parish Priest of the Mary Mother of God Kabarnet Parish of Nakuru Diocese.

Outside Kenya, Mons. Oseso has served as the assistant Parish Priest of St. Ambrose, Endicott, Holy Family, and St. Margaret, Syracuse, in the Archdiocese of New York, U.S.

Once he is Ordained a Bishop, the Kenyan-born Priest will serve as the fourth Local Ordinary of the 18,149 square-kilometer Diocese that was erected in April 1968.

The Diocese has a population of 614,043 Catholics, according to 2019 statistics, and is part of the Metropolitan See of Nairobi.

In his speech after he was announced Bishop-elect, Mons. Oseso expressed gratitude to the Holy Father for the appointment.

“I want to thank the Holy Father for entrusting this heavy responsibility upon me, but I believe in the men in this room and also those elsewhere, Religious men and women and our lay people that together, we will make it,” the Bishop-elect told members of the Clergy who gathered at St. Mary’s Pastoral Centre of Nakuru Diocese.

Bishop Kamau who has been serving as the Apostolic Administrator also expressed gratitude for the latest Episcopal appointment in Kenya and thanked the Clergy, women and men Religious and the Laity of Nakuru Diocese for their cooperation.
