Chronicle Heritage, the Phoenix-headquartered firm once recognized as the largest cultural resource management company in the United States, has shut down entirely, laying off all 108 of its local employees along with roughly 600 workers companywide. The closure took effect October 1 without any public announcement, leaving archaeologists and paleontologists recalled mid-project from active excavation sites around the world.
According to ABC15 Arizona, the company filed a Worker Adjustment and Retraining Notification with the Arizona Department of Economic Security confirming the layoffs of all employees at its midtown Phoenix office at 2025 N. 3rd Street. State WARN tracking records show the notice was officially recorded on October 5, listing 108 affected local employees, per LayoffTracker. Chronicle Heritage conducted archaeological reviews and other land surveys for developers and government agency clients, work designed to help those clients meet regulatory requirements before proposed developments could begin, the station's report notes.
From Phoenix Startup to National Powerhouse
Chronicle Heritage originally operated under the name PaleoWest, founded in Phoenix in 2006 by Tom Motsinger, and grew over two decades into a nationwide consultancy, according to the company's own history as cited by Chronicle Heritage. By 2026, the firm was widely recognized as the largest CRM firm in the country, operating more than 20 offices nationally and internationally across Europe and the Middle East while completing over 6,500 projects, as reported by Inc.
Private equity firm The Riverside Company invested in PaleoWest in 2022 as the company pursued growth and acquisition plans. That backing enabled PaleoWest to acquire Michigan-based Commonwealth Heritage Group in September 2022 and Four Corners-based Stratified Environmental and Archaeological Services in February 2023, folding multiple regional firms and hundreds of staff under one Phoenix corporate umbrella. The consolidated company rebranded under the single name Chronicle Heritage.
Regulatory Demand That Built the Business
The firm's commercial services were part of a regulatory environment involving preservation laws, including Section 106 of the National Historic Preservation Act of 1966. Chronicle Heritage conducted archaeological reviews and other land surveys for developers and government agency clients, work designed to help those clients meet regulatory requirements before proposed developments could begin.
The shutdown's timing compounds the blow for field workers. It coincided with the end of the primary U.S. archaeological field season, leaving hundreds of field archaeologists facing unexpected job losses during what is already a seasonal slowdown, according to posts cited from archaeologist killgrove.bsky.social on Bluesky.
Unanswered Questions
The closure left the future of major archaeological projects uncertain, Inc. reported. Some projects involving federal funding or permits require cultural reviews before development can proceed.
It remains unclear how active client contracts and pending regulatory filings will be reassigned to other firms, or what specific financial pressures triggered the sudden liquidation without prior public notice. For now, the 108 Phoenix employees named in the state WARN filing are left without jobs just as the broader archaeological field season winds down nationwide.
