About Alliant Resources Group

Alliant Resources Group, which operates as Alliant Insurance Services, is an insurance brokerage and financial services distribution company. Founded in 1925 and incorporated in 1999, the firm has grown into one of the largest insurance brokers in the United States through a strategy combining organic growth and numerous strategic acquisitions.

The company was formed when Alliant Resources Group merged with Robert F. Driver Company in 2001. Key figures in its history include John Addeo and William Robinson, who founded Alliant in 1999 with an equity partner, and Tom Corbett, who became Chairman and CEO in 2005. Under Corbett's leadership, the company expanded significantly, growing to over 4,000 employees in more than 100 offices.

Alliant offers a comprehensive portfolio of services, including property and casualty insurance, employee benefits, retirement programs, and risk management solutions. The company serves over 15,000 commercial clients across various specialized sectors, including public entities, Indian Nations, law firms, construction, and real estate. Its business model focuses on distributing specialty-oriented products and maintaining leading market positions in these niche areas. Revenue is generated through brokerage fees and commissions on the insurance and financial products sold.

The firm has actively acquired other companies to enhance its specialty expertise and geographic reach, such as Robert F. Driver Co., Gaddy Ward & Company Insurance Brokers, and Group Insurance, Incorporated. This strategy has been central to its expansion and ability to offer a broad range of tailored solutions to its clients.
