Obert Mukumbi was born on February 11, 1974 in Mashonaland Central Province where he also attended school. He was interested in wood craft and worked on that while he was still in school. Soon after school he was encouraged by his cousin Kennedy Musekiwa who was already an established and well-known stone sculptor.
Obert's works concentrate on issues of the day to day life of African people which he achieves from human expression in abstract and figurative form. He works on hard stones such as springstone, opal, cobalt and fruit serpentine. His work has been exhibited in many countries including the USA, Venezuela and Cuba.
