How it all started…

In 2002 Mr. Mark Bergmann and Mr. Tim Lawson joined forces to create LGC Inland Inc., and Logical Geotechnical Consulting (LGC), a unique idea in the geotechnical and environmental industry was born. Utilizing a simple approach of providing our clients leadership in the industry, integrity throughout our organization, dedication to the geologic and engineering profession, and very importantly service to our clients, LGC quickly became the largest geotechnical and environmental consulting firm in the entire Temecula Valley.

Throughout the early 2000’s, Logical Geotechnical Consulting continued to grow and add capabilities receiving laboratory certifications from the cities of Los Angeles and San Diego. Laboratory certifications were also obtained from CCRL (Cement and Concrete Reference Laboratory) and AMRL(AASHTO Materials Reference Laboratory). LGC expanded into construction materials testing and inspections services providing registered inspectors for concrete, structural steel, masonry, and many other construction related materials.

In 2012, LGC reorganized its ownership and management team and created LGC Geo- Environmental, Inc., providing Logical Geotechnical Consulting in the geotechnical and environmental fields. LGC Geo-Environmental, Inc. continues to provide unmatched leadership in the industry, personal integrity on ever project, and a longstanding commitment to service our clients with the utmost quality and responsiveness. We pride ourselves on being different by being fully committed, dedicated, and responsive to every client regardless of project size.
