AmTrust Financial Services has announced a signficiant expansion of its Excess and Surplus (E&S) division, adding senior industry talent and rolling out new product lines in property, environmental and builders risk.
The move consolidates the company's primary, excess, and environmental products into a new brokerage casualty group, creating an integrated platform aimed at driving growth in the specialty market.
According to the company, the E&S division is at an inflection point as part of a long-term strategy to make meaningful investments in talent and broaden offerings to better serve insureds. Over the past 18 months, AmTrust has added a number of experienced professionals to lead its expansion into new business lines while maintaining a focus on the specialty market.
Leading the new casualty brokerage group is Brian Mulvihill, who joined AmTrust in August 2025 after more than nine years at Crum & Forster Insurance. His roles there included work in construction and unified XS, as well as serving as vice president, excess & umbrella, head of wholesale East.
Kevin Sullivan, vice president of property, joined AmTrust in April 2024 to establish and lead the property group after more than 11 years as vice president at AXA XL.
In January 2025, AmTrust appointed Tom Kashickey as vice president of environmental. Kashickey brings nearly two decades of experience in the environmental insurance market, having held underwriting and leadership roles at Ironshore and AXIS Capital.
The builders risk group is led by vice president Rob Tricamo, who joined AmTrust in April 2025 after 11 years at Berkshire Hathaway Specialty Insurance, where he most recently served as vice president of construction property.
Together, Sullivan, Kashickey, and Tricamo will oversee the property, environmental, and builders risk product lines, adding further depth to AmTrust’s E&S expertise. They join an experienced E&S management team that includes Topher Fylak, vice president of E&S binding authority; Jackie Hennig, vice president of E&S unsupported excess; and Tom Hartnett, vice president of underwriting, E&S.
AmTrust also recently named Curt Fletcher as senior vice president to lead its new E&S Premier group, which will focus on complex casualty business distributed through a select group of brokers.
The expansion comes at a time when the E&S sector continues to see strong growth. Carriers have been turning to the market as a release valve for risks that do not fit within standard underwriting appetites, particularly amid persistent economic uncertainty, evolving environmental exposures, and rising claims costs in casualty lines. Property capacity has also remained tight following recent years of severe weather-related losses, pushing more business into the E&S space.
Against this backdrop, AmTrust’s broadened offering positions it to compete more aggressively in an increasingly crowded segment. By adding talent with deep experience across property, environmental, and construction-related risks, the company is seeking to capture opportunities as businesses and brokers look for specialised solutions beyond traditional markets.
