Worcester-based The Hanover Insurance Group Inc. has expanded its professional liability capabilities and product line and acquired Illinois-based Benchmark Professional Insurance Services Inc.

The company also has hired Robert F. Drohan to help build-out its professional liability product service and lead its miscellaneous professional liability business.

Drohan, a 30-year veteran of the insurance industry, previously worked at Colemont Insurance Brokers, Travelers Insurance Co., and Lexington Insurance Co., according to a statement.
The Hanover Professional Portfolio is a growing selection of professional and management liability products designed to offer the company’s agent partners an advantage and more opportunities to grow in their local markets.

Benchmark specializes in underwriting small- to mid-sized architects, engineers, interior designers, landscape architects and land surveyors.

The Hanover’s new architects and engineers program will offer a wide range of limit options (from $100,000 up to $10 million) and deductible options, including a $0 deductible option for small firms.

"The expansion of our professional liability capabilities is just one example of our firm commitment to investing in the people, products and services needed to be the best partner for growing independent agents," said Frederick H. Eppinger, chief executive officer of The Hanover. "By strategically adding distinctive capabilities, we are offering our partner agents new ways to strengthen their competitive position and grow their businesses over the long term."
