Experience when you need it most.

As a full-service consulting firm, Feffer Geological offers complete expert witness and forensic services for insurance companies and law firms encompassing a wide range of investigations.

Our principal Engineering Geologists and Geotechnical Engineers have experience that covers all of your technical needs.

Having worked on some of the largest cases in Southern California, our experienced personnel have been providing geotechnical support for litigation and insurance claims for over 20 years. Feffer Geological is hired by both plaintiff and defense attorneys for disputes involving landsliding, surficial failures, flooding events, slope creep, construction defects, construction change orders, expansive soil and settlement of structures.

Our trained consultants are fully licensed, designated expert witnesses who carry advanced degrees. We quickly assess and clarify geological and geotechnical issues and articulately relay all relevant information during meetings, mediation proceedings, arbitration hearings and court trials.
