Centennial Art Center Staff

Joshua Wagner

Josh Wagner serves as the Art Center’s Director and Supervisor for Metro Parks’ Visual Arts Division. Josh attended Union University, where he earned his Bachelors of Art (BA) degree with concentrations in photography and ceramics. After graduation, he moved to Nashville where he serendipitously encountered Centennial Art Center. Josh began teaching his own classes at the Art Center in 2003 after taking pottery classes with former instructor, Lena Lucas. In addition to teaching classes, Josh also worked as the Centennial Art Center Gallery and Pottery Studio Manager. He continues to teach an advanced level pottery class on Thursday evenings.

Josh views art as the expression of emotions and concepts –communication without the necessity of words. For him, these concepts come alive in objects, in moments and experiences. For the audience, each take-away is unique because no two individuals see the world exactly alike. Josh adds, “Although no one’s journey is identical, through art, we can construct a series of shared experiences. Art has the power to build community, bridging the gap between people from all walks of life. Let’s go make some art…and build community…together!”

In 2014, she completed with honors a 27 month Botanical Art Distance Learning Diploma Course from the Society of Botanical Artists in England.

She is excited by the challenges of communicating light and color with paint and brushes. What color is water in a glass? How does one describe the gentle contour of a white flower? How does one mark where a shadow begins and ends? Her garden is a research lab of sorts where she observes the small differences in shapes, colors, textures, and patterns of growing things. From painting and gardening, she has learned that the longer one looks, the more there is to see.
