Welcome!

Bill Lettis and several business partners, with decades of combined professional experience, have started a new earth sciences consulting firm specializing in engineering geologic, seismic and natural hazards investigations. We are headquartered in Walnut Creek, CA with additional offices in Valencia, CA and Augusta, GA.

Lettis Consultants International, Inc. (LCI) is dedicated to providing our clients with solutions to technically challenging earth science problems. LCI personnel have extensive experience conducting large, logistically complex, multi-disciplinary studies for critical facilities such as nuclear power plants, dams, ports, bridges, pipelines and LNG terminals. Many of these investigations were performed under strict QA and regulatory oversight. Our personnel have provided domestic and international consulting services on a multitude of high-profile infrastructure projects. As appropriate, we utilize or deploy the most modern computing and analytical tools available, and provide map and data products in whatever forms our clients require. LCI professionals develop unique solutions of the highest technical quality to satisfy our clients’ needs in addressing site characterization and licensing issues.

We at LCI look forward to working with you!

Sincerely,

Bill Lettis, Hans AbramsonWard, John Baldwin, Serkan Bozkurt, Kevin Clahan, Brian Gray, Andy Lutz, Steve Thompson, and Jeff Unruh, Scott Lindvall, Ross Hartleb, Melanie Walling, Frank Syms, Randy Cumbest, Mike Gray, Gabriel Toro, Robin McGuire, John Vlasity, and Julia Phillips.
