Secretariat, a leading global independent expert services and litigation consulting firm, has acquired Economists Incorporated. EI will operate as Secretariat Economists LLC, a wholly owned Secretariat subsidiary.

The entire team at EI is excited to join Secretariat and anticipates that the union of the two firms will allow the new entity to serve its existing clients all that much better while offering new clients an attractive new choice from among service providers.
