Atlantic Casualty Insurance Company

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 1990’s, the book had grown to over $100 million of premium in seven states.

These products are distributed exclusively through Managing General Agencies.
