About Us

We help employers find the solutions that will result in the reduction of workers’ compensation costs.

Atlantic Charter Insurance Company is one of Massachusetts’ leading workers’ compensation insurers.

The group consists of Atlantic Charter Insurance Company, Endeavour Insurance Company, and Independence Casualty Insurance Company. Our mission is to offer employers solutions that will provide them with the insurance protection, professional guidance, and legal support necessary to reduce the long-term cost of workers’ compensation claims.

We’re different because we invest significant engineering and consulting resources in advising our clients on managing employee injuries with an emphasis on employer involvement.

We believe that when an employer maintains contact with the injured employee throughout the disability period, they create an atmosphere of goodwill, enhance morale, and help ensure that the employee is back on the job sooner. With more than 25 years of experience, our team looks forward to getting to know you and your corporate culture, and partnering with you to manage every aspect of your workers’ compensation program.
