Marsh has completed its previously announced acquisition of Accel Holdings, a diversified independent insurance and advisory firm headquartered in Waverly, Iowa. Financial terms of the transaction were not disclosed.
Accel will operate within Marsh Agency, where the deal expands the firm’s Upper Midwest presence in Iowa. The acquisition also adds retirement and wealth advisory capabilities, alongside Accel’s experience in agribusiness insurance.
All Accel Group employees have joined Marsh Agency and will continue working from their existing locations. Marsh said the acquired business will complement its current commercial and personal insurance, employee benefits and advisory services.
The Accel Group was founded in 1936 and further established its legacy through a strategic merger with Millhiser Smith Agency in 2018, which was founded in 1928.
By bringing together high-quality firms with strong leadership, deep client relationships, and specialized capabilities, we continue to expand a platform designed to serve the middle market at the highest level.
Matt Stadler, President of Marsh Agency
Today, the firm provides commercial and personal insurance, employee benefits and agribusiness solutions. It also offers wealth management and retirement advisory services, giving Marsh Agency a broader range of services across its Iowa operations.
