• About Us
HERITAGE. EXCELLENCE. INNOVATION.
We Are Okrika Grammar School
Okrika Grammar School was founded in 1940 by the Church Missionary Society (CMS) under the auspices of Bishop A. M. Gelsthorpe and the Anglican Diocese of Okrika, making us one of the oldest and most distinguished secondary schools in Rivers State and the wider Niger Delta region.
For over 85 years, OGS has stood as a beacon of academic excellence, moral formation, and community pride built on the founding conviction that education should shape character, sharpen minds, and produce leaders.
"We are more than a school. We are a legacy, and we are building something extraordinary on top of it."

For over 85 years, OGS has stood as a beacon of academic excellence, moral formation, and community pride built on the founding conviction that education should shape character, sharpen minds, and produce leaders.
"We are more than a school. We are a legacy, and we are building something extraordinary on top of it."
A History of Greatness
When the school opened its doors in 1940, its first principal, Mr. Ifediora Oli, admitted 60 pioneer students, 30 of whom were Okrika indigenes. Among that founding cohort were His Majesty King S.P.U. Ogan, Ado XIII, the late Amayanabo of Okrika, and Hon. Justice Jotham Fiberesima (JP), who served as the school's first Senior Prefect. From its very first day, OGS was producing royalty and leaders.
Over the decades, Okrika Grammar School has produced some of the most distinguished figures in Rivers State and Nigerian public life. The OGS alumni roll is not simply a list of names; it is a record of impact across every sector of Nigerian society.
Chief Rufus Ada-George — Former Governor, Rivers State
Sir Gabriel Toby — Former Deputy Governor, Rivers State
Hon. Justice Sika Aprioku
Dakuku Peterside — Former Director-General, NIMASA
His Majesty King S.P.U. Ogan, Ado XIII — Amanyanabo of Okrika
Hon. Justice Jotham Fiberesima JP — First Senior Prefect
A Legacy Restored
Following a comprehensive, state-funded renovation officially commissioned on March 13, 2025, OGS has been transformed into a world-class learning environment equipped to deliver education at the highest standard.
This is the foundation we stand on, and it is the standard we are committed to restoring and surpassing. We are restoring the Pride of Okrika and building the next generation of Niger Delta innovators.
