Jan O'Sullivan is a Dublin-based painter who began her career in her mid-forties and is now nearly ten years into it. In an interview published on the Singulart blog on October 9, 2026, she explains that she has been merging the themes she has developed — abstract landscapes, seascapes, figures and interior schemes — into single canvases rather than treating them separately. Her best-known subject is an iconic Dublin scene: the two red-and-white striped Poolbeg power station chimneys on the Dublin coastline. She has worked the image for two years, abstracting it and removing it from the coastline, often rendering it in a fauvist manner folded into interiors-style compositions. The work she names as most representative of her current direction, "Blush Cadence," shows her moving away from her early fauvism toward a more neutral, textured palette aimed at the quiet-luxury tastes of interior designers. O'Sullivan is candid about her unorthodox training: a career in IT and banking gave her, she says, transferable tools of process, iteration and revision, and she treats each finished canvas as a launched product. Her studio runs on what she calls a conveyor-belt system — three canvases at a time, abstract underpaintings laid on Sunday night, photographed Monday morning, then worked through the week so that by Friday they are finalized for sale. She has never sought gallery validation, focusing instead on homeowners and interior stylists as her market. A formative encounter with a disinterested buyer collecting a gift purchase taught her never to guess at a customer's motives — a philosophy she now distils into the lesson that every painting needs only one buyer.
