Artist, Stone carver and Conservator

While working as a painted surface conservator, Allison discovered stone carving in 2005. Immediately drawn to the laborious, painstaking and careful process of bringing words and images to slate, Allison adopted carving as her primary media. She is one of only about a dozen artists in America still practicing this ancient art of carving letters by hand. Allison has worked as a gravestone conservator for MCC since 2006. She best describes her work …”as a conservator I also have a kind of motherly relationship to the stones, where I pull them up out of the ground, prop them back up, wipe off their faces and send them on their way to hopefully last another 200 years.”
