Assurex Global has elected The Miller Group, a Kansas City-based commercial insurance and risk advisory firm, as its newest Partner Firm.
Dean Hildebrandt, president and CEO of Assurex, credited the firm's multigenerational track record for the selection.
"The Miller Group's deep-rooted expertise, dedication to client relationships, and multigenerational commitment to excellence make them an outstanding addition to our Partnership," Hildebrandt said.
Founded in 1961 by Bob Miller, The Miller Group has grown across three generations, from second-generation leaders Sean and Matt Miller to current CEO Amber Miller Manning, who took over in 2023 and has expanded the firm from its original focus on construction-sector commercial insurance and surety into employee benefits and broader risk advisory work. Miller Manning framed the partnership around preserving what already works.
"Joining Assurex Global strengthens the resources behind our advice while preserving what clients value most about The Miller Group: senior involvement, practical guidance, and accountability," Miller Manning said, adding that the move carries particular value as the firm continues expanding its property and casualty capabilities.
What distinguishes Assurex Global's model from much of the brokerage consolidation activity elsewhere in the industry is that it isn't an acquirer at all. Firms that join the Assurex Global partnership remain independently owned and locally led, gaining access to the network's roughly 100 member firms spanning six continents, along with shared market intelligence, specialty resources and multinational client capabilities, without selling any equity or ceding local control.
That structure puts Assurex Global in a genuinely different category from the private equity-backed roll-up strategies driving much of the industry's recent M&A activity, offering family-owned and closely held firms a way to access global scale while keeping ownership and succession entirely in-house.
Assurex Global has been adding firms to that network steadily throughout 2026. The network elected Nebraska's UNICO Group as a partner firm in March, and added Czech brokerage OK HOLDING in April to strengthen its coverage across Central and Eastern Europe, alongside Ireland's Hastings Insurance in February.
Founded in 1954, Assurex Global has built a partnership whose member firms consistently rank among the industry's largest; 21 Partner Firms appeared on Business Insurance's 2026 list of the 100 largest brokers of US business this year, and 18 made that publication's separate broker trends rankings.
For family-owned and independently operated brokerages weighing their own growth and succession options, The Miller Group's move illustrates a genuine alternative to the sale-to-private-equity path that has dominated much of the industry's consolidation narrative in recent years.
A firm like The Miller Group, now navigating its third generational leadership transition under Miller Manning, gains the specialty resources and multinational relationships typically associated with scale, deeper property and casualty capacity, broader benefits expertise, and cross-border servicing for clients with multinational exposures, while keeping the local accountability and ownership structure that a sale to a consolidator would otherwise dissolve.
For agency owners specifically weighing succession within their own family or leadership team rather than an external sale, Assurex Global's continued expansion offers a concrete precedent worth understanding alongside the more heavily covered private equity roll-up model.
