Rocio Ballester (born in Buenos Aires, 1994) is an Argentinian pottery artist currently living and working in Maui, Hawaii. She studied Visual Arts at Regina Espacio de Arte (Buenos Aires, Argentina) and stoneware ceramics with Andrea Espel. While doing the specialized training with Espel, Rocio discovered her passion for the art of pottery and started using clay as her material for artistic expression.

Ballester moved to Maui in 2016 and joined the Hui No'eau Visual Arts Center. There, she continued her training and took multiple courses with well- known potters such as Jennifer Owen and David Vitarelli. In 2018 Rocio founded DelMar Ceramics and has been selling her pottery in craft fairs and high-end decoration stores since then.
