Gregory Gatti worked with one of his clients to expand its property insurance program so that it can grow with the company, still meeting its needs year after year as the client scales. The client is growing rapidly so Gatti has planned ahead for the next 5-10 years in addition to managing the current risks.

Given the London market’s appetite for his client’s specific risk profile, Gatti added some Lloyds’ capacity at the last renewal. Gatti also brought the client to the Bermuda market and expects to add Bermuda capacity in the excess property program layers in 2025.

Notably, he saved the client more than $1 million in premium savings by restructuring the property program to write named wind and storm surge exposure with one carrier, instead of on a quota share basis.

One of Gatti’s clients summed up their relationship and Gatti’s contributions to the insurance industry, saying, “Greg (known as GG) truly is “one of a kind.”

“He brings his intense personality to what sometimes can become a very dry industry. I’ve often described him as the global ‘mayor’ of the insurance industry, kissing babies, hugging underwriters, and maintaining close personal relationships with people from Singapore to London, Bermuda, and across the U.S. Hidden underneath that boisterous and engaging exterior is a deep and intense knowledge of the property insurance market.”
