Mosocho · Kisii County · Established 1957
Cardinal Otunga High School - Mosocho is a Catholic-founded boys' boarding secondary school on the Kisii–Kisumu Road, built on discipline and academic excellence since 1957.
Our Story
Cardinal Otunga High School - Mosocho was established in 1957 following a request from the then Kisii Diocese Bishop, His Eminence Maurice Cardinal Otunga.
Located at Mosocho, along the Kisii–Kisumu highway, the school was primarily meant to host missionaries. It has since grown into one of the region's well-known Catholic-sponsored boys' boarding secondary schools, guided to this day by its founding principle: "Use common sense."
