Justina's master's degree in early American material culture from the Winterthur Program at the University of Delaware complements well her interest and love of sharing Philadelphia with visitors. At the Philadelphia Museum of Art, she works as Site Manager for Mount Pleasant and Cedar Grove, two historic homes in Fairmount Park administered by the Museum. She also designs programs and trains guides to share the Museums' collections with the public. Working with Museum curators, preservation professionals, and other stakeholders, she advocates for public access to and interest in local historic sites.
