Chineme and Aghaegbuna Ozumba have professional and academic experience spanning many disciplines. 

The "Uche and Uzo Say it in Igbo" series grew from their efforts to teach their children Igbo (Ibo) language. The aim is to fill the language gap existing among Igbo children in diaspora, who grow up not speaking the language.

The series is a total immersion approach with simple everyday words and sentences. The words are spoken by characters that children can identify with. The books have companion videos for effective pronunciation, and activity books for learning exercises.
