Mr. AbramsonWard is currently President and was a founding member of Lettis Consultants International, Inc. He is a California Certified Engineering Geologist with over 25 years of experience in geologic and seismic hazard assessment for critical facilities including dams & levees and appurtenant structures, pipelines, canals, tunnels, bridges, ports, and nuclear plants. He applies his broad technical skills to projects that vary widely in both scale and complexity while serving alternatively as a technical project participant, project manager, and reviewer. He is highly skilled at integrating data from diverse sources to develop site characterization models or constraints on the activity of fault deformation or other geologic processes that honor the variability of data available, consider data gaps and limitations, and account for associated uncertainties.
