Oh began her art career at Hornsey College of Art in London. After gaining her degree in graphic design, she went on to have a fifteen-year career as an award winning art director in advertising, working in various international agencies in London, Lagos, Nairobi and the Far East. A major launch for a clothing company led to a series of commissioned works of art which awakened her artistic abilities and interest in colour energy. After a couple of years freelancing, she returned to London in 1995 with several private commissions and took to painting full time. As an intuitive painter, she developed her own language and found her voice in her chosen medium of soft pastels on paper.Oh has exhibited internationally and her shows include mixed and solo exhibitions in Lagos, Istanbul, London, Los Angeles, Miami and New York to name a few. Her paintings are also housed in corporate collections in Nigeria and Togo, and private collections in Nigeria, Kenya, the UK and the USA. A permanent showcase can be seen in the award-winning restaurant and healing rooms at the Mount Haven Hotel in Cornwall (UK). She is now based in Wales, and runs 101 intuitive painting workshops with clients.
