Cass Breen is a London based artist. Her current practice focuses on sculpture, works on paper and photography.  Her work is informed by cultural background and personal history. She is interested in how religious artefacts contain power beyond their material properties, embodying elegance and grotesqueness at the same time, and the way dark messages hide behind beautiful images. Her choice of material guides the making process and is intrinsic to the interplay of form and idea. 

She is involved in several art collectives including Sedici, Kennington and Fold with whom she exhibits regularly. She was invited as a guest artist to show with the Critical Edge Collective in its Handbag Factory show in May 2025.  In 2024 she completed a residency at the Pouch Cove Foundation in Newfoundland focusing on developing her practice. 

Cass is an Irish artist, born and raised in Dublin. She has lived in London for many years, having completed a fine art degree in the early years. She has an MA in Fine Art with distinction from the City & Guilds of London Art School.

Cass was head of faculty for Visual Arts at City Lit in London for 10 years, leading the highly influential department that encompasses the fine and applied arts. She moved on to become Deputy Principal at Morley College in Waterloo where she stayed for 5 years before leaving to focus full time on her art practice. Since then, she has maintained a London studio.
