As our business becomes even more global in scope, and as we look to expand MSA’s presence and brand in China and other growth markets, his experience will strengthen the expertise of our board and help MSA continue to achieve success. I would also like to express my gratitude to Tink Campbell for his 13 years of service to the MSA board. His counsel and judgment over the years has helped us improve in many ways and we are very grateful for his dedication and contributions to MSA.”
