Who we are

Who we are

Gallagher WGA is the union of two leading insurance brokerage firms; William Gallagher Associates (WGA) and Arthur J. Gallagher & Co. (Gallagher). Combining broad industry expertise, we share the goal of providing enhanced and expanded solutions to our clients.


The WGA firm was founded in Boston in 1983 by a group of insurance professionals who wanted to provide a unique style of highly-specialized insurance brokerage services to companies operating in the most dynamic industries. Over the past 30 years, WGA became one of the country’s leading independent brokerage firms, employing a first-class team of insurance professionals dedicated to providing service and expertise to clients in complex industries. The specialty areas of the firm ranged from the fast-paced world of technology, pharmaceuticals and life sciences, to the broad and complex operations of financial risk, private equity, healthcare, renewable energy and environmental services.

In August 2015, WGA merged with Arthur J. Gallagher & Co. (NYSE: AJG), a global leader in insurance brokerage and risk management services with client-service capabilities in more than 140 countries around the world. Our strategy has not changed; WGA was built by focusing on small and middle market entrepreneurial business, and helping the fast-growth, dynamic companies within our core industries. WGA and Gallagher combined their operations to better serve our employees and our clients. The firms became united to create a stronger organization that continues to lead the industry in client service and ethical business practices.
