“Citadel is 100% employee-owned. We want to share what we make with those that make it, and that includes everyone. Our roles may be different, but they’re equally as important.”

“I think highly of our competition, and I use competition loosely because I think there are a lot of ways that we can collaborate, to extend our geography or skill base for example.”

“What changed with the pandemic is that the indoor environment became much more important. There were real health issues associated with the spread of diseases and pathogens.”

“Whether the hazard is biological, physical, or chemical, ventilation is crucial. And understanding your building’s systems is crucial for the prevention of these issues.”

“Focus on indoor air quality overlays all of our service lines, ensuring a complete, integrated set of services for our clients. Collaboration between various practice areas is key.”

“Employers are concerned about retaining and recruiting staff. They want to articulate what they’ve done to ensure safety in the work environment, but what are the best options?”

“Wildfire-related challenges are certainly impacting our clients. We can’t control the situation, but we can control how we prepare and respond with some key questions.”

“Two big themes within the built environment are 1. Sustainability and 2. Health and Safety. Where are these two trends aligned? And where is there tension? And what can be done?”
