Since earning his master of fine arts degree from American University in 2008, the 39-year-old painter has made a name for himself in the local art scene as a purveyor of extravagantly hedonistic visual confections. After making his initial splash with a series of murals celebrating the cheesy milieu of the roller-derby arena and its helmeted, booty-shorted heroines, Oberndorfer gradually shifted gears. He is best known now for paintings that offer a virtual concession stand of sugary treats: chocolate, chewing gum, Peeps candies, ice cream, lollipops, donuts and, in his latest body of work, popsicles.
