At the time of his recognition as Engineer of the Year 1994, Equilibrium (Summer 1994) noted: "Those who have worked with John will tell you that he epitomizes a bridge engineer. His state-of-the-art technical ability is cutting edge, and designing bridges is his passion. ... He was a member of the ATC delegation to the New Zealand Workshop on Seismic Design of Highway Bridges (ATC-12) and was a delegate and speaker to the 7th Joint US-Japan Bridge Workshop in 1991 and 1993 in Tsukuba City, Japan. John has led two People-to-People tours, to China and Russia/Eastern Europe, where he presented papers, facilitated discussions, and assisted with this exchange program where different countries had the opportunity to meet and discuss bridge engineering issues."
