LAKEWOOD, Colo. -- Aventia, an industry-leading platform providing comprehensive environmental service solutions, announced the acquisition of St.Germain, an environmental consulting, regulatory compliance, and engineering firm. 

Headquartered in Maine, St.Germain serves industries throughout New England and the United States, offering a range of compliance and engineering services, including site remediation, hydrogeological investigation, solid and hazardous waste management, environmental compliance, energy and petroleum management, site planning and development, training, and Sentry EHS®, an online compliance management and tracking tool.

Bernhard Capital Partners, a services and infrastructure-focused private equity management firm, established Aventia—formerly Environmental Systems Group—in July 2022.

"By combining our expertise and deep understanding of environmental challenges with Aventia's extensive resources and network, we look forward to further enhancing and expanding our strategic services, as we continue to help our clients achieve their environmental and operational goals."

"The addition of St.Germain represents another strategic milestone in Aventia's growth, strengthening the capabilities of our platform to become a diversified, one-stop environmental solutions provider," said Chris Dillon, Partner at Bernhard Capital. "This expansion enhances our nationwide reach while further establishing Aventia as a leader in environmental services."
