"The secret to our organization’s success lies in its culture,” noted McCausland during his speech. "We became the leader of the U.S. packaged gas business by employing a customer-centric approach to local decision making and giving our Airgas associates the autonomy, responsibility, and resources to create value. We have built a platform for growth second to none, all supported by the people who make up the best team in the business.”
