Citadel EHS Strengthens its Footprint by Acquiring Aurora Industrial Hygiene Services

In a significant strategic move aimed at enhancing their service offerings in environmental health and safety, Citadel EHS has officially acquired Aurora Industrial Hygiene, Inc. This noteworthy acquisition, announced by Broadview Group on June 1, 2026, marks an important chapter for Citadel EHS as it expands its capabilities in the industry.

Details of the Acquisition

The acquisition combines the strengths of both companies, effectively broadening Citadel EHS's expertise within the environmental, health, safety, and sustainability (EHS&S) consulting framework. With Aurora Industrial Hygiene's established presence in California, particularly in San Diego and Los Angeles, Citadel will notably increase its geographic coverage and service proficiency.

Founded in 1996 by Karen Shockley and Grace Rinck, Aurora has garnered a reputation for providing high-quality environmental consulting services. Their expertise spans various essential areas, including industrial hygiene, OSHA compliance, occupational health, hazardous materials consulting, and lead and asbestos services. This acquisition symbolizes Citadel EHS’s commitment to delivering comprehensive and technical EHS solutions to its clients across various sectors, including healthcare, education, construction, and government.

Expanding Opportunities

The integration of Aurora’s diverse team of certified professionals—such as Certified Industrial Hygienists (CIHs) and Certified Safety Professionals (CSPs)—into Citadel’s existing operations is anticipated to amplify their service capabilities. This team is recognized for their dedication to client and employee satisfaction, qualities that align seamlessly with Citadel EHS's corporate values.

Davis Malone, Vice President of Broadview Group, stated, "This acquisition builds on our strategy to foster Citadel EHS's growth and enhance its offerings. Aurora brings not only a strong reputation but also deep technical expertise which is crucial for our mission." He emphasized the compatibility of organizational cultures between Aurora and Citadel EHS, aiming to create an environment of shared values and collaborative spirit.

A New Chapter

For founders Karen Shockley and Grace Rinck, this acquisition is a pivotal transition after nearly three decades of guiding Aurora's success. They expressed their enthusiasm about entering a partnership with Citadel, citing shared values of quality and responsiveness as key components of their decision. “We were looking for a partner that would not only respect the legacy we built but also offer our employees and clients more opportunities,” they mentioned. With the expanded resources available through Citadel EHS, they are poised to maintain the personalized service clients have come to expect.

Looking Ahead

With its enhanced technical capabilities and broader geographical reach, Citadel EHS stands to reinforce its position as a leader in environmental health and safety consulting across the nation. Loren Witkin, CEO of Citadel EHS, shared his excitement about the acquisition, highlighting that the synergy between the two firms will lead to improved service delivery: “Aurora represents an incredible strategic fit. Their commitment to quality and client relationships will significantly bolster our ability to serve existing and future clients.”

As Citadel EHS integrates Aurora's services into its operational model, it is set to continue its course toward becoming a comprehensive consulting solution for environmental health, safety, and sustainability in the United States and beyond.
