Who is an Expert Witness?
An expert witness is a professional who is very knowledgeable, trained or experienced on a certain field which is involved in your case.

Examples include:
- Medical professionals who can describe how injured you are and whether this happened due to the accident.

- Vocational experts that evaluate the impact of your injuries on your employment capacity.
- Economists that do mathematical estimations of long-term financial losses.

Expert witnesses even interpret these complexities to simple and understandable information. They may testify or not and make the difference between confusion and clarity to the judge or jury.
