Quintin was born in Colchester, Essex, in 1974 and raised in the nearby town of Manningtree. He spent much of his early life around the Dedham Vale 'Constable Country'. He studied Geology at Leicester University, a Masters in sedimentology at Reading University and gained a PhD in carbonate sedimentology from The Open University, based in Milton Keynes. However, art has remained a lifelong passion and he is largely self-taught. After experimenting with most mediums he now mainly paints in oils to best convey his realist style. His subject matter includes landscapes, pet portraiture and still life and more recently people portraits. He has been providing commissioned artwork for 15 years mainly finding time during evenings and weekends.
He lives in Aberdeenshire with his wife, Cheryl, daughter Rosalind.
