PTA was founded by professional archaeologists whose goal was the integration of scholarship and innovation into compliance-driven projects in archaeology, history, built environment studies, cultural landscapes, and preservation. Advancements in technology over the past 40 years have changed the way we do business, in many ways, but the mission has not changed. More than a statement on paper, PTA’s staff lives the mission daily, delivering intelligent and cutting-edge performance to meet client needs in a timely and cost-effective manner. A key aspect of PTA's long-term success is the company-wide recognition that we are only as good as our last product. We believe in our mission and apply it to each project. Clients in the private and public sectors turn to PTA for cultural resources management needs because they know the job will be done well, on time, within budget, and without costly delays. This is a guarantee we give each client and PTA will commit its staff and resources to provide rapid response and customer satisfaction for every project.
