Hon. B.Sc., QEP
David is Vice President and Project Director in RWDI AIR, based in Calgary, Alberta. While his expertise is in air quality and hazard and risk assessments related to industrial facilities, he's really a people guy. He spends much of his time making sure we communicate clearly with our clients and they communicate clearly with their stakeholders. As required, David appears as an expert witness and testifies in hearings on behalf of his clients.
"Clients want to be successful in communicating their message," says David, "especially in the public domain. It improves their chances of getting regulatory approval. Our job is to have the best technical experts, ensure we meet their timelines, and give clients the technical data and professional opinion they need to make their case."
David is a skier, hiker and horseback rider. He plays hockey and likes to garden and work around what he calls his "acreage." "I am most proud of the growth of RWDI AIR into Canada's largest provider of air quality, hazard, and noise studies, and our strong reputation for balanced expert technical judgment."
