Overview
Citadel EHS has acquired Aurora Industrial Hygiene, strengthening our industrial hygiene practice and expanding our reach across Southern California.
Founded in 1996 by Certified Industrial Hygienists Karen Shockley and Grace Rinck, Aurora built a respected practice spanning industrial hygiene, OSHA compliance, asbestos and lead services, and indoor air quality assessments, serving clients from offices in San Diego and Los Angeles.
What this means for clients
The two firms share a client-first approach and a deep bench of technical talent. Aurora's team, values, and long-standing client relationships carry forward under the Citadel EHS banner, while clients gain access to Citadel's full environmental, health, safety, and sustainability (EHS&S) service line.
We're proud to welcome the Aurora team to Citadel and to continue the work they began nearly three decades ago.
