About William

William H. Thielen is a visual artist working across mixed media, painting, drawing, print, and sculpture. His practice centers on geometric systems, color interaction, and the psychological effect of repeated forms. His work moves between tightly structured compositions and intuitive shifts that introduce imbalance, surprise, and rhythm.
