Jeff was born and raised outside of Worcester, Massachusetts. After graduating from the University of Arizona in 1975 with a degree in accounting, he moved to California and went to work as an accountant for Santa Fe International Corp., then one of the largest oil and gas drilling contractors in the world. Due to strong industry dynamics in the late 70's, numerous employment opportunities developed within the organization. In a span of five years, Jeff gained valuable experience in accounting, cash management, strategic planning, financial analysis, and mergers and acquisitions. After the takeover of Santa Fe by the national oil company of Kuwait in 1981, Jeff was transferred to Texas as acquisitions manager for the company's exploration and production division. Over the following three years, he was engaged in the evaluation and acquisition of over $1 billion of producing properties for the company.
In 1985, Jeff left Santa Fe to produce and market a unique set of research reports covering over 200 publicly traded oil and gas companies. This was done at first through his own company and then in conjunction with an investment banking boutique based in Denver, Colorado that specialized in the oil and gas industry. It was through this work that Jeff met Rick Rule, who ultimately recruited him in1992. Since then, Jeff built and serviced the largest client group at Global, acted as CEO for nearly nine years, and now acts as CEO and adviser to Sprott Asset Management USA.
