In 1983, he became manager of commercial and industrial products and was named general manager of marketing operations in 1985. In 1987, Callahan was elected president of Warren Petroleum Co., a Chevron subsidiary.

Prior to the merger with Texaco, Callahan was named an executive vice president in 2000. He assumed his current position upon the formation of ChevronTexaco Corp. on Oct. 9, 2001.
