Born in November 1962, Mons. Kamomoe started his Priestly formation at St. Mary's Propaedeutic Seminary, Molo, in Kenya’s Diocese of Nakuru.

He had his philosophical and theological studies at St. Augustine's Senior Seminary Mabanga in Kenya’s Catholic Diocese of Bungoma and St. Matthias Mulumba Senior Seminary Tindinyo in the Catholic Diocese of Eldoret, Kenya, respectively.

Mons. Kamomoe was ordained a Priest for the ADN in June 1994. Since then, he has served as assistant Parish Priest, Parish Priest, and member of the College of Consultors of ADN, among other Priestly duties.

Until his February 13 Episcopal appointment, the Kenyan-born Catholic Priest has, since 2008, been serving as the Administrator of the Holy Family Minor Basica; he has also doubled as the Family Life Chaplain of Nairobi Archdiocese. 

He holds a master’s degree in Psychology from Tangaza University College (TUC), and a doctorate in Counselling Psychology from the Nairobi-based Catholic University of Eastern African (CUEA), an entity of the Association of Member Episcopal Conferences in Eastern Africa (AMECEA).
