About GM Insurance Underwriters
A Florida agency built for real-world risk
Our story and mission
GM Insurance Underwriters was founded to give Florida clients a better kind of insurance experience. We believe coverage should be practical, clearly explained, and matched to the risks you actually face. Our mission is to help contractors, business owners, and families make confident decisions with an advisor who stays in their corner long after the policy is issued.
From the beginning, our work has centered on Florida’s unique mix of weather exposure, fast-growing communities, and high-stakes job sites. That local understanding shapes how we shop coverage and how we
guide clients through renewals, audits, and claims questions.
Leadership with construction focus
Experience that benefits contractors
Founder and principal agent Geoff Munn built his career in commercial insurance and has specialized in
commercial construction since 2014. That background is the reason construction clients make up the majority of our agency today. We understand contracts, additional insured requests, and the pace of Florida jobs, whether you’re working in Jacksonville’s urban core, the Gulf Coast, or along South Florida’s building corridor.
Our specialty also helps
other business owners. The same attention to detail that protects job sites translates into sharper coverage for professional offices, retail operations, service companies, and property-related businesses.
Independent by design
More carrier options, clearer choices
As an
independent insurance agency, GM Insurance Underwriters isn’t tied to one company’s products. We work with multiple A-rated carriers, which lets us compare pricing, coverage forms, and endorsements to find the right fit.
Independence also means flexibility when your needs change. If a carrier shifts in
Florida’s market or your risk profile evolves, we can move with you and keep the program on track.
Rooted in the community
Local involvement that’s part of who we are
We’re proud to be
based in Jacksonville and to stay involved in the communities where our clients live and work. Construction is a relationship business and so is insurance. Whether we’re supporting local initiatives, industry groups, or neighborhood events, we show up because this is home.
That commitment matters to our clients. Many found us through friends, colleagues, or fellow contractors, and we work hard to
earn that kind of trust on every account.
