The school, Mercy Girl’s Secondary School, Ogbor Hill, as it is popularly called, was established in January 1988 by his Lordship RT. Rev. Dr. A.G . Nwedo C.S. Sp. ( Of Blessed Memory ) The Bishop Emeritus of Umuahia Diocese.

The school started with a single block as it was not originally designed for a secondary school, but for a Day Care Center and to have been managed by Aba zone Of the Catholic Women Organization, CWO under the leadership of Mrs. V.P. Erokwu.

When the Bishop Emeritus conceived of the school, he met the C.W.O and sold his noble idea to them and with every humility,they obliged him the use of his parcel of land for the laudable project. Thus, the school was formally handed to the Bishop on the care of DMMM Rv. Sisters, and the first principal was Rev. Sister Mary Ugochukwu  Agbakwuru.

In accordance with the order of sisterhood, Rev. Sister Ugochukwu did not stay for a long time as she was posted out to serve in another capacity in Lagos and Rev. Sister Adline Ojukwu of blessed memory was brought to carry on from her predecessor stopped. This was on 9 May, 1998. It is worthy of note to mention here that the presence of the late principal marked  a turning point in the wheel of progress of the young school, to the extent that even now she is no more, her legacy knows no bounds in the hole of Aba and it’s environs, for her numerous achievements in the school which ranged from high morals to academic excellence. Her contribution towards the growth of the school and promotion of reality cannot be over emphasized as they linger from generation to generation. Other principals like Sr.M. Laboure Okoroafor, Sr.M. Jacqueline Oranye, Sr.M. Anne Ngadu, Sr. Marie Humbline Nwaokoro, and  the present principal, Sr. Chris Anthony Ndikani have continued to raise the schools banner of greatness higher and higher.

Initially, the citing of the school in Aba attracted a lot of criticism as people argued that there were many schools in Aba, and so the young school would lack patronage. But, the proprietor paid deaf ears to all these and went on with the project, and today, all the critics have been proved wrong as the school which started with less than one hundred students has now grown like the mustered seed.

We as members of Mercy Girl’s Secondary Schools, Aba Ogbor Hill Community recognize the fundamental rights of each student to be respected, nurtured, cared for and protected.
