Zenna Tagney was born in Gunnislake, east Cornwall, and grew up in Tywardreath, mid Cornwall. She has a foundation degree in Art & Design and a BA (Hons) in Contemporary Crafts from University College Falmouth.

Zenna creates ceramic sculptures using porcelain clay, a material associated with Cornwall's china clay country. She incorporates found objects such as old wood and vegetation into her pieces.
