ESIS Overview

ESIS Experience and Expertise

Founded in 1953, ESIS was one of the first companies to handle workers compensation claims on a third party basis. Originally a member of The Pacific Employers Group, ESIS became part of INA in the 1960s and then CIGNA as the result of a merger between Connecticut General and INA in 1982. On July 1, 1999, ESIS became part of the ACE Group. As of January 14, 2016, ESIS is part of the Chubb Group. ACE Limited acquired the Chubb Corporation, creating a global insurance leader operating under the renowned Chubb name.

ESIS employs approximately 1,300 professionals in nine regional centers and 15 major claims offices, as well as local representatives in select jurisdictions. We take our fiduciary responsibilities seriously and are proud to manage over $2.5 billion of customer losses and over 320,000 new claims annually.
