Lawley Insurance, a regional insurance broker serving New York and New Jersey, was ranked for the first time among the Top 50 agencies in the country in this year’s annual listing in Business Insurance magazine, the company reported.

Buffalo, N.Y.-based Lawley’s “planned, systematic growth” allowed it to move up 29 spots since 2006. It ranked 50th in 2010. The magazine’s rankings are based on all brokerage revenues, the commissions and fees from the sales and servicing of commercial and personal insurance and employee benefits.

Lawley’s planned growth was a result of several factors, including its continued expansion of branch partner offices across the Northeast, according to a company statement.

“Over the past several years, we have invested in key resources to enhance our value proposition for our client base,” said Lawley Principal William Lawley Jr.

The company continues to focus on workers’ compensation and employee benefit solutions, alternative risk financing (including captives), claims management and loss prevention, said Lawley Principal Christopher Ross.

Lawley serves industry groups that include construction and surety, automotive, nonprofits, public entities and health care.

Lawley Insurance, incorporated in 1955, has New York branches in Amherst, Batavia, Fredonia, Rochester, Westchester County and a branch in Florham Park, N.J.
