About Northern Insurance


Northern Insurance is a full-service insurance agency, serving individuals and businesses in Will and DuPage Counties.

The roots of Northern Insurance Service begin with the Cornolo Insurance Agency, established in 1927 by Joe Cornolo in the back of a Lockport grocery store. In 1996, the agency was renamed Cornolo & Thompson and continued to expand its reach throughout Will and DuPage Counties. In 2005 and 2006, Cornolo & Thompson moved to its current Joliet location and adopted the Northern Insurance name to facilitate future expansion.

Northern Insurance was formed in 2005, bringing the collective efforts of several insurance professionals under one organization to provide streamlined service, better technology, and advanced product offerings to our current and future clients. Today, Northern Insurance is a diversified insurance agency serving individuals and institutions throughout the Midwest.
