Citadel EHS Strengthens Its Position in the Industry

On June 1, 2026, Citadel EHS, a prominent environmental, health, safety, and sustainability consulting firm, made headlines with its acquisition of Aurora Industrial Hygiene, Inc. This strategic move is designed to enhance Citadel's offerings and regional presence in California, where both firms have established significant footprints.

Founded in 1996 by Certified Industrial Hygienists Karen Shockley and Grace Rinck, Aurora Industrial Hygiene has built a strong reputation over the last 30 years. The firm is known for delivering technically sound and client-focused environmental health and safety consulting services across various sectors. These include commercial, industrial, healthcare, education, government, and construction, among others.

Aurora’s service offerings encompass a wide range of industrial hygiene and occupational safety consulting services. These include OSHA compliance, hazardous materials consulting, indoor air quality assessments, exposure monitoring, and workplace safety support, making the firm a respected player in the state of California.

The acquisition aligns seamlessly with Citadel EHS’s strategic goals. Loren Witkin, the CEO of Citadel EHS, emphasized the cultural and operational fit between the two organizations. "The addition of Aurora Industrial Hygiene represents a strategic and cultural fit for Citadel. This marks an important step in our journey to provide our clients with exceptional service while expanding our technical capabilities to help them meet their environmental, health, safety, and sustainability goals," he stated.

The merger is expected to enhance Citadel's technical expertise in industrial hygiene and safety practices. Aurora's skilled team, including Certified Industrial Hygienists (CIHs), Certified Safety Professionals (CSPs), and Certified Asbestos Consultants (CACs), will join Citadel’s existing workforce, enabling a wealth of knowledge transfer and innovation.

Karen Shockley and Grace Rinck expressed their enthusiasm for the partnership, noting it was essential to find a suitable home for their firm’s values and client relationships. They were looking for a partner that would ensure that their commitment to quality and responsiveness would continue, and they found that in Citadel. "Joining Citadel allows Aurora’s team and clients to benefit from expanded resources and broader capabilities while maintaining the personalized service they know and trust," commented Shockley and Rinck.

This acquisition is not only about expanding services but also about creating a more robust network for existing clients and new prospects. Citadel EHS, headquartered in Southern California, already boasts a diverse range of services including industrial hygiene, environmental compliance, building sciences, and safety consulting. The addition of Aurora's capabilities will significantly enhance Citadel's capacity to serve clients across the nation effectively.

Citadel EHS operates under the auspices of the Broadview Group, a St. Louis-based investment company that supports growth-oriented teams. This backing has allowed Citadel to pursue opportunities like the acquisition of Aurora, aiming to create long-term value through strategic insights and operational efficiency.

With the merger finalized, both companies are looking forward to a promising new chapter where they can leverage their combined strengths to offer unparalleled services in environmental consulting. In a time where compliance and environmental stewardship are more critical than ever, this acquisition positions Citadel EHS as a leading player in the environmental sector, ready to tackle complex challenges facing businesses today while ensuring a healthy and safe working environment.

As the landscape of environmental health and safety continues to evolve, the integration of Aurora Industrial Hygiene into Citadel EHS promises to deliver enhanced service offerings that can meet the growing demands of various industries. This acquisition could inspire other firms to rethink their strategies in an industry that increasingly requires a commitment to sustainability and compliance.

In conclusion, the acquisition of Aurora Industrial Hygiene by Citadel EHS could mark the beginning of exciting developments in the realm of environmental consulting. With strong leadership, a focus on technical expertise, and a commitment to client service, the future looks bright for both companies and the clients they serve.
