The Summit Story

Strength in numbers

Because of the strong work ethic of our employees, a dedication to excellence and our philosophy to “do the right thing,” Summit has grown exponentially over the years.

  • Less than 10 years after opening our doors, we topped the $100 million mark in total annual standard premium managed and employed more than 150 people.
  • In the 1990s, we managed the first workers’ comp insurer in Florida with a statewide approved managed-care plan. We continue to maintain our in-house managed-care program and proprietary provider network for our insurers—which has expanded to nine states.
  • In 1998, we became a wholly owned subsidiary of Liberty Mutual, a Fortune 500 company and one of the largest insurance companies in the world. This gave an A rating to our affiliated insurers Bridgefield Casualty Insurance Company and Bridgefield Employers Insurance Company, which are managed by Summit.
  • From 2001 to 2007, we doubled our number of employees.
  • By 2007, Summit reached the $1 billion mark in premium under management and employed more than 1,000 people across 10 states—making us one of the largest providers of workers’ compensation insurance products in the Southeast.
  • In 2014, American Financial Group Inc. purchased Summit and its related companies from Liberty Mutual. Summit continues to operate under its own brand as a member of Great American Insurance Group, whose roots go back to 1872 with the founding of its flagship company, Great American Insurance Company. Great American Insurance Company has received an “A” Excellent or higher rating from the A.M. Best Company for more than 100 years.
