Tegerin was born and raised in Cardiff. He studied Graphic Design at Kingston Art College, London. His work is greatly influenced by the mountains and quarries of North Wales, where his forefathers lived and worked. He is also influenced by the remnants of the coal mining industry in the South - another industry where there are family links. He attempts to capture the patterns and marks created by man and nature on the landscape, by using a variety of mediums. Some of his work represents specific places, while other works are an abstract interpretation of a number of places, memories and maps, using marks, symbols and colour to convey this. Tegerin has exhibited his work in galleries in Cardiff, London, Newcastle, Berlin and New York. He has also had a number of photography books published, which have all sold out immediately.
