Our Travel Expense Policy

Did you know we do not charge for travel expenses on projects outside of Southern California?

As a national expert witness consulting firm we realize we have to compete with local consultants on out-of-town projects with more than just a higher level of expertise and ethics. Therefore, we do not charge for out-of-town travel expenses and travel time for projects outside of Southern California. We charge for local travel only.
