Geoffrey Callahan

Geoff Callahan (b. 1987) is a San Francisco-based abstract artist whose work explores the tension between structure and spontaneity, memory and erasure. With a background in fine woodworking and an evolving practice that spans painting, mixed media, and printmaking, his approach to composition is deeply tactile—each piece is built as much as it is painted.

Callahan’s work is informed by the interplay of thought and presence, often using repeated forms, layered textures, and reclaimed materials to investigate the shifting landscapes of memory. His recent paintings incorporate geometric blocks and gestural marks that act as both structure and obstruction, evoking the ways we construct and navigate meaning.

His work has been described as a meditation on perception and permanence, where the history of the material is as integral as the paint applied to it. Whether working on canvas, found objects, or large-scale installations, Callahan’s process reflects a search for equilibrium—balancing precision with raw intuition, the seen with the hidden.
