He was the driving force behind the GIA's international expansion, transforming it into a global leader in gemological education and research, with a network of 10 laboratories and seven schools operating across 10 countries. His leadership was further acknowledged in 2002 with the prestigious Richard T. Liddicoat Award for Distinguished Achievement, and in 2013, he was elected to the GIA Board of Governors, solidifying his enduring impact on the institution and the wider gemological community.
