Why Cornerstone?

Florida’s insurance market is unlike anywhere else in the country. Rising premiums, carrier exits, and reduced coverage options have left too many homeowners, drivers, and families without the protection they actually need.

We’re selective about the carriers we work with. Cornerstone partners only with companies that have proven experience operating in Florida — or newer carriers backed by highly experienced management teams. We don’t chase volume. We specialize in building comprehensive, customized coverage packages around the real-life situations our clients face every day.

Cornerstone is a proud member of the Florida Association of Insurance Agents and the Trusted Choice Insurance Network, and holds an A+ rating with the Better Business Bureau. We focus exclusively on personal lines insurance — because doing one thing well means our clients always get our full attention.

Agent James Bonn was very helpful in getting Tower Hill home insurance on time when I had a short time period before my current insurance expired. He was with me all the way through until I was connected to my new service.

I had for a 4 point inspection and wind mitigation done. They approved the policy. My house insurance goes through my mortgage holder. So Tower Hill got paid through them, and I cancelled my old insurance carrier. Then after about a month and a half, I get a cancellation notice. They sent their own inspector in and reported a couple shingles were missing and a piece of soffit square was missing and rust on a decorative post on my porch. My roof was over 10 years old, so I quickly got the roof replaced and took care of the other issues as well before the cancellation deadline. They worked with me and not only did they keep the policy from getting cancelled, my premium is now lower because of the new roof.

I just switched my homeowner's insurance through Joshua Gleaton with Cornerstone. I had been with my previous insurer for 32 years. Josh was outstanding to work with. He was responsive, easy to work with and provided me with tremendous savings (Cut my insurance in half). I only wish I had called him years ago.

Jan 2026- Highly recommend James! He helped me set up my homeowners and flood policies and made everything easy to understand as a first time home buyer. He was responsive, professional, and truly helpful every step of the way. Great experience overall.

Josh was incredibly helpful with helping me to find the perfect car insurance! He was able to answer all of my questions promptly and helped me to find the best rate possible without sacrificing coverage. and I cannot leave out Pammie, who helped with all of my customer service needs. What a GREAT team!!!

Kyle Wilson from Cornerstone Insurance was recommended to me for purposes of purchasing home insurance on my new home in Sarasota. As a current New England resident, I was not familiar with many Florida agents and am thankful I was introduced to Kyle. He made the insurance purchase process quick and easy and was extremely attentive - despite me reaching out during the week between Christmas and New Year's Day. For those of you who have resided in the Northeast and "expect" quick, reliable service as well as timely responses to your messages, I highly recommend you contact Kyle. I am also very pleased with the pricing of the insurance and the opportunity to customize the coverage I was seeking.

Kyle Wilson was extremely helpful with my home insurance request, he will reply to your questions fast, with accuracy and he works on weekends, holidays, day and night. Thanks Kyle for handling my policy!

Joshua Gleaton at Cornerstone helped me with saving almost $2k/year on my homeowners insurance while increasing my Law & Ordinance coverage to 25% (from 10%) and replacement cost for contents rather than assessed value. I suggest everyone in FL shop their HO insurance as this was a big savings with increases in coverage that will make a huge difference if ever needed. I dragged Joshua along for months as I had several other priorities and he patiently stuck in there and got me set up with new insurance. I recommend you call him.

Kari Tate was a pleasure to work with. I needed to switch over to a new policy and she made the process quick and painless, keeping my premiums low but still retaining similar coverages.
carlos D.
I recently purchased an insurance policy, and I couldn’t be happier with the experience. From the very beginning, my agent was friendly, patient, and incredibly knowledgeable. They took the time to understand my needs, explained all available options in simple terms, and never once made me feel rushed or pressured.

What stood out the most was how transparent and attentive they were. They answered every question clearly, helped me compare plans, and made sure I fully understood the coverage before making a decision. Their professionalism and genuine care made the entire process stress-free.

Thanks to their guidance, I now have a policy that fits my budget and gives me peace of mind. I truly appreciate their support and would highly recommend them to anyone looking to purchase insurance!

It was so easy! No stress.
