DBSS came into existence as a result of the good works that Don Bosco Training Institute Onitsha has been doing and is still doing since 1992 for the citizens of our great nation Nigeria especially those coming from South East region and beyond. Its trained students are successful wherever they are posted in companies. As a result, many well meaning individuals, some of who are DBSS parents\guardians today solicited that Don Bosco Youth Centre also do something for the younger ones. Salesians’ consideration which reflected much on the situation and realities of the people living around Ibolo Obosi, Ugwuagba, Awada, Okpoko and Fegge environs met the above request with a positive and favourable consideration.

With this, DBSS came into existence in the year 2007. The fame with which this school is known for today has been and is still attracting students of post primary school ages from environments that are far from above mentioned ones. The curricular and extra-curricular activities that the school has been engaging in both inside and outside the school advertise the school even when such is not solicited for.
