Geppe mainly works with acrylic on canvas. In great curtains of color, he folds in light and dark. Each work exhibits usually two standout colors such as pink and orange or turquoise and purple that pierce through a heavier backdrop of black or neutral tone. Oftentimes white blots over these colors the way rust or mold would, giving the paintings a timeworn look. Geppe's lines are in the vein of abstract expressionism. Though no figures can be perceived, each painting is titled after a concept such as Grounded. He describes his work as impulsive and enjoys when it provokes a reaction in people because he establishes a closer relationship with humanity. The viewer interprets the meaning and feeling behind each painting by the combination of colors and size of the stalactite-like lines gripping the canvas.
