About

Southern Insurance Underwriters, Inc. (SIU), based in Alpharetta, Georgia, is a certified Managing General Agency serving independent agents throughout the southeast for over fifty years.

On July 1, 1964, W.C. Duesenberg, Sr. purchased the Atlanta branch office of Kurt Hitke & Company and created Southern Insurance Underwriters, Inc. Building on the foundation started by Mr. Hitke, SIU specialized in Non-Standard Auto coverage and other specialty coverages including Commercial Trucking and Senior Drivers. Over fifty years later, the list of coverages has expanded to include: Commercial Property & Casualty, Commercial Transportation, Personal Property, Professional Lines and Standard Lines.

SIU offers a broad range of property, casualty, and transportation products and specializes in hard to place, specialty and excess & surplus lines risks. With an experienced staff of underwriters, the scope of risks that can be underwritten ranges from the simplest property risks to highly sophisticated self-insured programs. Today, SIU represents more than 150 admitted and non-admitted specialty companies, Lloyd’s of London, and several standard companies.

Family owned and operated, Mr. Duesenberg, Sr. enlisted his son, Wes Duesenberg, Jr. to join the corporation in 1976. Together, they grew business into a group of companies, Southern Insurance Companies (SIC), employing 200 people and steadily increasing the personal and commercial lines written premium year over year. In 2014, the 50th anniversary of SIU, Wesley C. Duesenberg, III (Tripp) was named President of SIU. The family tradition continues as Tripp leads the next generation of underwriters.

Innovative technology has always been a key factor in the success of SIU. Today, SIU offers agents the ability to quote online using numerous raters for Commercial Lines, Personal Lines and Standard Lines.

Southern Insurance Underwriters, Inc. is represented by over 2,500 Independent Agents, primarily in Alabama, Florida, Georgia, Mississippi, South Carolina and Tennessee. In addition to the corporate office in Atlanta, SIU has a branch office in Lake Mary, Florida.
