Olaniyi Afonja is a Yoruba actor from Oyo state and he is popularly known as Sanyeri. His father is an artisan while his mother is a trader. He had his primary education at St. Michael Primary School, Oke-Ibo, Oyo Town, Oyo State, and later attended Durbar Grammar School, Oyo Town, Oyo State. He started his acting career sometime in 1991/92 but his parents didn't approve of him being an actor. They enrolled him as an apprentice-tailor, but he usually ran away from training to rehearse with members of the drama group because he didn't believe that there was any future for him as an artisan.
