"The most rewarding aspect of the work is the challenge of determining how to improve efficiency, operations, and occupant comfort in existing buildings using cost effective and innovative solutions. It’s not always as simple as a replacement or upgrade; sometimes it’s about addressing how this system can function better as a whole. The vast expertise of the team at Prism is critical to the success of identifying opportunities and implementing solutions."

-- Stephen Kooiman
