Insights

Specialized Expertise The Sullivan Group emphasizes niche specialization in property, casualty, professional liability, and management liability with focused programs such as healthcare management liability and community association insurance. Sales opportunities exist by offering tailored, deep-dive wholesale and underwriting support to retail producers seeking specialist coverages.

Reinsurance Focus As a reinsurance intermediary handling specialized treaty reinsurance and property facultative placements, there is potential to expand relationships with MGAs, program managers, and administrators who need capacity and bespoke reinsurance structures for their programs.

Program Management The company provides program management consulting and binds authorities, indicating opportunities to partner with managing general agencies and program administrators seeking efficient underwriting governance, contract underwriting, and binding capabilities under structured programs.

Growth and Scale With revenue in the mid hundreds of millions and a nationwide footprint, The Sullivan Group presents a scalable platform for cross-sell of wholesale brokerage, underwriting, and risk transfer solutions to mid-market retailers and niche insureds through existing distribution networks.

Competitive Landscape Operating alongside large multi-line brokers with substantial employee bases, there is room to differentiate on specialized expertise, faster decision-making, and targeted programs for healthcare, community associations, and garage coverage to win market share among independent agencies and specialty programs.
