Sarah Sheehan

Prior to graduating from the University of Connecticut with a B.A. in Anthropology, Sarah Sheehan began her archaeological career in 2008. Her experience in over 20 states (Eastern and Western) has familiarized her with diverse landscapes, materials, cultures, and methodologies and their integrated relationships.

Sarah has conducted an immense amount of routine CRM fieldwork on prehistoric and historic projects in all phases. Outside average expectations of the CRM realm, Sarah has held multiple positions that advanced her experience on a wider, adaptive scale. Sarah has exhumed human remains on a 19th-century cemetery relocation project in Philadelphia, PA. Her duties involved analyzing age, gender, and accuracy of remains before preparing for final reinternment, while training others on the process. Sarah was also employed with the Office of the Chief Medical Examiner of NYC following the 9/11 attacks on the World Trade Center for the recovery of human remains and evidence surrounding the 9/11 attacks. In 2012, Sarah was the head archaeologist for a team of UXO, GIS, and geological technicians. She served as the sole identifier and recorder of cultural material in the Snowy and Medicine Bow Mountain Range. Sarah has also been responsible for maintaining positive rapport between tribal members and contractors/clients on controversial projects.
