Jonathon Appell
Atlas Preservation

Since Jonathan was a child he always had a high mechanical aptitude to build and repair. From bicycles to cars, violin making, cabinets, building construction trades, and eventually monument installation in 1986. Throughout the 1990’s Jon ran a cemetery contracting company that performed excavation, monument installation, foundations, & restoration.

Working in and around some of the oldest graveyards in America Jon became interested in helping preserve the historic stones. Since the late 90’s he sought out specialized knowledge and training to enhance his ability to conserve the older and more fragile gravestones. Currently Jon performs specialized projects and also conducts workshops nationally in collaboration with towns, states, historical societies, and cemeteries.
