Management at Hawaii Geophysical Services


Lelan Hein at Hawaii Geophysical Services

Lelan Hein, President

Hawaii Geophysical Services (HGS) is owned by Lelan (Lee) Hein, who has over 35 years experience as a licensed contractor. During those 35 years, Lee gained experience and knowledge in multiple construction technologies. As a result, HGS is able to bring products, technologies and services to the marketplace for the benefit of its customers.

Lee’s background as a plumbing contractor led to the founding of HGS in 2002. As a swimming pool and plumbing contractor engaged in both leak detection and sewer repair, it was necessary to locate both conductive and non-conductive piping. A consequence of that work was the investigation of new technologies to add to the company’s “tool box.” Customers drove the expansion into the variety of technologies that HGS employs today, as well as the wide range of services it offers.
