Philip J. Williams

Philip has an extensive engineering and operations background. He received both a Bachelor of Science in Mechanical Engineering and a Masters in Business Administration from the University of Arizona. He spent seven years in the U.S. Navy in the Naval Nuclear Propulsion Program. Among his duty stations was a two year shore tour at the Knolls Atomic Power Laboratory in West Milton, NY where he was responsible for training operators on theory and operation of nuclear-mechanical systems and was able to help perform end-of-life testing on the S8G prototype. His sea duty rotation was aboard the USS Gato (SSN 615), one of the last 594s to be decommissioned.

Philip has worked for both large and small privately held companies in several capacities. In the Quality arena he has developed failure analysis programs and conducted numerous Quality audits both here and in Asia. Philip has managed both maintenance departments and high volume assembly lines both in the U.S and in Maquilladoras in Nogales, Sonora where he was responsible for implementing lean manufacturing principles. Other responsibilities have included Purchasing where he implemented automotive style supply contracts and worked closely with Suppliers, Marketing and Engineering New Product Development Groups to bring new products to market, and Production Product Engineers to implement cost savings and improve products.

At HGI Philip is responsible for overseeing the Finance, Quality, Sales, HR & Administrative functions.

James B. Fink, Ph.D.

Dr. Fink is the President and founder of hydroGEOPHYSICS, Inc. He is responsible for the overall company management and maintains an active role in consulting, equipment and software development, including the development of the High Resolution Resistivity (HRR) geophysical method. He has taught geophysics at the University of Arizona as contract faculty and was an adjunct faculty member for several years. He is currently active in the development of the SafetyNetTM system, which promises to economically provide early warning detection of seepage problems within earthen dams.

Jim's education includes a dual-major B.Sc. Degree in Geophysics and Geochemistry from the University of Arizona; an M.Sc. degree in Geosciences, cum laude, from the Bernard Price Institute of Geophysics at the University of the Witwatersrand in Johannesburg, South Africa; and a Ph.D. in Geological Engineering and Geohydrology from the University of Arizona.

Dr. Fink is a registered geophysical engineer and registered land surveyor in Arizona, a registered professional engineer in New Mexico, and a registered professional geologist in Wyoming.

He has nearly 40 years experience in the industry and academia. Dr. Fink has a unique experience in the development and application of geophysics towards environmental remediation, geotechnical studies, mineral exploration, and hydrogeologic projects. During that time he developed the theoretical basis, algorithims, and field procedures for High Resolution Resistivity (HRR).

Robert L. McGill, EIT.

Mr. Rob McGill is our Engineering Project Manager. After initially obtaining a business degree in 1989 and working in the marketing/sales arena , he returned to university in 1994 to complete a Geological Engineering degree. He promptly joined HGI where he oversees daily operations of the company. Rob is mainly responsible for preparing proposals, writing reports, and developing scope of work documents. Rob is also involved with general marketing, business development, project procurement and subsequent management of engineering projects. Rob has both a B.A. Degree in Business-Marketing from West Texas State University (now West Texas A & M) and a B.Sc. Degree in Geological Engineering from the University of Arizona. He is currently pursuing a Masters of Engineering Degree from the University of Arizona.

He has nearly six years experience in the environmental-geophysical industry and another ten years of sales and marketing experience. During these years, he has gained unique experience in the application of geophysics towards environmental remediation, ground water issues, mineral exploration, and other related fields.
