Harold Olejarz began his career as a sculptor. He worked in wood, creating sculptures ranging from abstract waves to figural sculptures inspired by Greek sculpture. Olejarz, active in the Soho cooperative gallery movement exhibited at 14 Sculptors Gallery in the late 1970’s and 1980’s. He also reviewed Soho gallery exhibitions for Arts Magazine during that time. In the late 1980’s and 90’s Olejarz created wearable sculptures and was active as a Performance Artist. He installed himself, as a living sculpture, on streets, in museums and public spaces across the country, performing in numerous festivals, galleries and museums. Olejarz received two fellowships from the New Jersey State Council on the Arts.
Digital imaging has fascinated Olejarz since 1990 when he first explored image manipulation with early digital tools like ColorIt! and early versions of Photoshop. His early digital images included a series of scanned images in which he used his hands and objects as “performers” on a flatbed scanner. These images created a bridge from Olejarz’s performance work to his digital imagery. 
Olejarz was awarded a public art commission by NJ Transit. For this commission he created two etched glass block windscreens, installed at the Pavonia/ Newport Light Rail Station in Jersey City, NJ. Currently, Olejarz is exploring digital image making outside of the rectangular frame. He uses his photographs as source material to create circular, collaged images that repeat and rotate slices of photographs. The images suggest mandalas and kaleidoscopes.
