Expert Witness Directory
Every discipline placed for California, Washington, and Oregon litigation, grouped by the question it answers. Where a specialty is governed by law that differs materially from one state to the next, it has a dedicated page for that state.
What disciplines can be placed for a West Coast matter?
Thirteen: medical standard of care and causation, forensic pathology, toxicology, and forensic psychology; financial, forensic accounting, business valuation, and vocational and economic loss analysis; structural engineering, architecture, construction site safety, and real estate appraisal; and insurance claims practice. All are available in all three states.
Themis Expert Witness, LLC operates as a managed expert network. Dr. Alban personally handles emergency medicine and medical causation matters; for every other discipline he identifies, vets, and manages an independently credentialed expert, then stays involved through report review and trial preparation.
The grouping below is by the problem counsel is trying to solve rather than by job title, because the discipline a matter needs is frequently not the one it first appears to need. A fall from height with a disputed injury mechanism is a construction safety question, a medical causation question, and a vocational loss question at the same time; a business interruption denial is an insurance claims-handling question and a forensic accounting question. Part of what the complimentary screening does is establish which of those is load-bearing.

How a placement actually happens
Nothing on this page is a self-service database, and that is deliberate. An expert list is only useful once someone has worked out which discipline the matter turns on, and that is a conversation rather than a filter.
The first call is a conflict check and a preliminary screening conversation, at no charge. Counsel describes the claim, the posture, and the schedule; the discussion identifies the discipline the issue points to, confirms availability and conflicts, and says what an opinion in that discipline would realistically be built from. Where the materials provided do not appear suitable for expert review in the discipline counsel had in mind, that is said in the screening call. The engagement process sets out each stage in full.
Screening does not include legal analysis, evaluation of claims or defenses, calculation of deadlines, or any view on whether a lawsuit is viable.
Complimentary consultation

Preliminary screening is complimentary. Send the posture of your matter — jurisdiction, claims, and the schedule you are working under — and Dr. Alvaro Alban, MD, MBA will identify the expert discipline the issue points to, check availability and conflicts, and tell you candidly whether the materials look suitable for expert review before you retain anyone.
