The Riverside Company-backed PaleoWest, a cultural resource management firm, completed the acquisition of Stratified Environmental and Archaeological Services, an environmental consultancy firm. Financial terms were not disclosed. “SEAS represents an attractive opportunity to expand PaleoWest’s services into the Four Corners region. M&A continues to be a top priority, and we plan to target investments that would complement PaleoWest’s existing service lines and expand its geographic footprint," Loren Schlachet, Riverside Managing Partner.
