NSI Insurance Group, one of the largest independently owned risk management and insurance firms in Florida, announced the acquisition of Mutual Insurance Group (MIG), further advancing NSI’s growth strategy and reinforcing its commitment to superior client service.
Florida’s insurance market, long challenged by costly hurricane claims and excessive litigation, is showing signs of stabilization in 2025. Legislative reforms enacted in 2022 and 2023 have addressed lawsuit abuses, attracting new insurers and leading to rate stabilizations and reductions. Despite these advances, Floridians continue to face higher premiums and ongoing underwriting challenges in a market reshaped by consolidation as firms scale to meet complex coverage demands.
“We are pleased to welcome Mutual Insurance Group to NSI Insurance Group, as we continue to expand our presence across Florida, especially in key vulnerable markets” said Oscar Seikaly, CEO and Chairman of NSI Insurance Group. “By acquiring companies that share our core values and vision, we are building a stronger, more innovative platform. This enables us to deliver comprehensive insurance solutions tailored to our clients’ evolving needs while expanding our service footprint throughout the state.”
Mutual Insurance Group, based in Miami, has built a strong reputation for offering a wide range of insurance products. This acquisition further expands NSI’s footprint across Florida while retaining the personalized service and strong carrier partnerships both companies are known for. MIG will continue to operate under the NSI brand, with its leadership team playing key roles to ensure a seamless transition and deepen client relationships. Together, they combine their strengths to provide exceptional service, backed by solid carrier relationships and deep local market expertise.
“This partnership with NSI marks an exciting new chapter for Mutual Insurance Group,” said Alex Crespi, Vice President of MIG. “NSI’s enhanced expertise in personal insurance and strong relationships with top-tier carriers have expanded the coverage options available to clients, allowing us to deliver innovative insurance and risk management solutions that truly benefit our clients.”
Client service lies at the very core of both NSI Insurance Group and Mutual Insurance Group, which is especially critical given today’s complex and changing insurance landscape. Both firms prioritize personalized attention and trusted guidance to help clients navigate evolving risks and market challenges. This client-centered focus is reflected in NSI’s outstanding Net Promoter Score (NPS) of 85 to 90, significantly higher than the insurance industry average of 20 to 30. Fueled by this dedication to service and innovation, NSI has achieved remarkable growth, doubling in size roughly over the past few years while maintaining its commitment to innovation, service excellence, and client success.
