Omari Sulaimann (Nickname Dogo) was born in 1980 in Nakapanya, Tuduru.
Dogo attended primary school up to grade 7. Further education was impossible because of lack of money. He earned his living in a small store until 1997, when he joined the Tingatinga Cooperative in Dar es Salaam. Iddi Issa became his teacher.
His favourite animals are flamingoes, which he keeps painting very often and which sell well.
