A repeat on IBA’s Elite Agencies list, Alliant is among the 15 largest insurance brokerages in the country. The company is still working to expand operations and grow its business, having made several acquisitions and added a number of industry veterans to its team this year. This October, Alliant acquired Hecht Group to add to its employee benefits portfolio and gain more clients in Portland, Oregon. The company also offers risk, industry and co-brokered solutions, as well as consulting services for property valuation, HR and risk control.
