Our Story

SINCE 1851…

In 1851, “The A.W. Jillson Insurance Agency” began writing fire and life insurance in Willimantic, CT. The agency was then purchased by A.B. Adams in 1862. Eventually, some new talent was brought into the agency, with George Elliot and Stanley Sumner joining the firm in 1926. Later, Stanley’s brother Homer would buy Mr. Elliot’s interest and in 1947 the agency would take on the name “Sumner & Sumner”. Since that time, we have continued to grow with the industry and our community. Today, we represent over 30 insurance companies and are poised to continue serving our clients for another 165 years.
