Atlantic Casualty Insurance Company with Green Mountain Agency

As you know, the Auto-Owners Insurance and Concord General Mutual Insurance Affiliation was approved in 2017. Auto-Owners has also acquired Atlantic Casualty Insurance Company, a superior excess & surplus lines carrier. 

As a Concord General Mutual agent, you have access to Atlantic Casualty Insurance Company through Green Mountain Agency (GMA) in the States of Vermont, Maine and New Hampshire. In addition, your production through GMA with Atlantic Casualty will count towards your growth incentives with Concord.

We are proud to represent Atlantic Casualty Insurance Company and offer our services for all your specialty insurance needs. We are an Elite Agency™ with Atlantic Casualty, enjoying expanded binding authority over the regular agencies. We have been serving retail insurance agencies in the State of Vermont, and in our expanded territory, as a family owned and operated wholesale insurance/managing general agency since 1976.

If you are already a customer of GMA, we thank you for your continued business and support. If you have never done business with us before, we welcome you to give us a try and find out why our knowledge and service are second to none. During this time of growth for these fine carriers, we are ready and willing to make personal visits to your office to discuss what we at GMA have to offer to you and your customers.
