Atlantic Casualty Insurance Company

Our Story

Who Is Atlantic Casualty?

Atlantic Casualty Insurance Company (Atlantic Casualty) was formed by Strickland Insurance Group (SIG) in 1983 to underwrite a substantial book of non-standard personal auto. By the late 1990s, the book had grown to over $100 million of premium in seven states. In 1998 the decision was made to refocus the company in commercial products. Our current product lines include Commercial General Liability, Commercial Package, Inland Marine, Ocean Marine, Commercial Property, Boiler and Machinery, and Commercial Auto (NC only). These products are distributed exclusively through Managing General Agencies. In January 2016, Atlantic Casualty and SIG were acquired and became part of the Auto-Owners Insurance Group. Auto-Owners Insurance Group has been in business for over 100 years and has been ranked among the Fortune 500 for over 13 years. Written premium for the group is over $10 billion annually, with an A.M. Best rating of A++ (Superior).

With offices in Goldsboro, NC; Hartford, CT; Scottsdale, AZ; and Richmond, VA; Atlantic Casualty has positioned itself to better serve its agency force and has authority in fifty states including Washington, DC. Hard work and solid results over the past 40 years have earned Atlantic Casualty an A+ (Superior) IX (financial size) rating from A.M. Best. Atlantic Casualty offers our agency partners excellent insurance products, state-of-the-art technology, financial strength, and stability. We also offer one other benefit that few companies can and this is access on a daily basis to the leaders of this company. We are honored that some of the finest wholesalers and general agencies in the country represent Atlantic Casualty.
