Frechette commented: “By increasing the depth of Patterson’s senior management team, these organizational changes will further strengthen our focus on our largest business, the growing North American dental supply market. At the same time, our new management structure will enable me to devote additional time to long-range strategic issues and policy. I will continue to be responsible for our Webster Veterinary Supply unit.”
