About Us

Petra Resource Management (PRM) was started in 2012 as a DBA of Petra Products, Inc., a California corporation founded in 1985. PRM is a Supplier Clearinghouse certified Women Business Enterprise (WBE) and a California Department of General Services (DGS) certified Micro-Small Business providing professional cultural resources management services.

While PRM is a relatively new company, we are not short on credentialed, experienced, and qualified personnel who are established and recognized experts in CRM compliance and practice. PRM has available a full range of field equipment and is capable of conducting numerous projects concurrently, including construction monitoring, survey, and excavation. Field documentation is aided by the latest technology available including ArcGIS and Trimbles with sub meter accuracy.

PRM has access to a laboratory fully equipped to process, analyze, and curate all sizes and manners of collections. The lab is also outfitted with binocular microscopes including specialized microscopes for paleoethnobotany, lithic use-wear, and ceramic analysis. PRM knows that by using the most contemporary technology, both in the field and in the laboratory, we can provide the most accurate data for our clients and research.
