From building a refinery from the ground up in Saudi Arabia to assignments in Japan, Brussels, New York, Illinois, Texas and Virginia, Jim brought excellence and dedication to every project. He formed enduring friendships with colleagues around the world and remained closely connected to a group of fellow retired engineers who met weekly for lunch, affectionately known as the “ROMEOs”—Retired Old Men Eating Out.
