Delma began painting in the early 60s. After retirement, Delma converted a storage building on her property into a pottery and painting studio, where she has since spent most of her hours happily indulging in her art. Her first formal presentation of her artwork was a group show in the Wenatchee Gallery, arranged by her college instructor, Sarah Spurgeon, in the early 60’s. Since then, Delma has been regularly exhibiting paintings and pottery in various galleries around Washington State. Delma earned two Master’s degrees at Central Washington University as a Ford Foundation Scholar, on in English and the other in Art. With a major in painting and drawing, and a minor in sculpture. On a sabbatical, Delma later earned the required course credits for the MFA degree. In 2004, Delma was invited to the Larson Gallery to have a Forty-Year Retrospective Exhibition of both painting and pottery. Delma has received several awards and honors during her many years as an artist. 

Delma was also involved with the Yakima Herald-Republic, writing an art criticism column.  Although she has retired from teaching and directing, Delma says she will never retire as an artist.
