Duffy Insurance Does It Again! Agency Announces 11th Acquisition

September 16, 2024 by AC Editor


Fourth-generation owned Cowan Insurance Agency Joins Duffy Family of Agencies

Duffy Insurance Agency, based in Lynn Massachusetts, has acquired The Cowan Insurance Agency of Haverhill, MA.

Fourth generation agency principal, Stefanie (Cowan) Guillemette, has led the family insurance agency in recent years. Since 1938, Cowan Insurance has served the insurance needs of individuals, families and businesses across Massachusetts.

“I am happy to welcome Cowan Insurance Agency, its staff and customers into the growing Duffy Family of Insurance Agencies. The customers of Cowan Insurance Agency will continue to enjoy in-house customer service with a strong emphasis on personal relationships. Cowan customers will enjoy additional product offerings and insurance company options here at Duffy Insurance. I couldn’t be more excited to begin working with Stef and The Cowan Team,” said Marc Duffy, President of Duffy Insurance Agency.

A Message from Stefanie (Cowan) Guillemette:

“On behalf of four generations of the Cowan family that make up Cowan Insurance Agency, Inc. I am thrilled to announce that we will be merging with the Duffy Family of Insurance Agencies. Duffy Insurance 2 will not only continue our legacy of helping our clients and community but will enhance these relationships through broader carrier access and outstanding customer relationships. Our values of putting the customer first and supporting family-based relationships are at the forefront of both Cowan and Duffy’s shared values. We look forward to welcoming our customers, both old and new to the future of Duffy Insurance. I look forward to servicing our accounts along with Jessica who will be joining me at the Duffy group. We will continue to be the same friendly faces and voices our customers are accustomed to working with,” said Stefanie.

The Duffy Family of Insurance Agencies

Founded in Lynn, Massachusetts in 1996 by the late Paul Duffy and currently led by Paul’s son Marc Duffy, Duffy Insurance Agency is a family insurance agency that services personal and commercial insurance customers throughout Massachusetts. Duffy Insurance prides itself in offering a flexible customer experience that is valued by both modern and more traditional customers. All customer service is done in-house (never via 3rd party service centers or automated phone systems). Duffy strives to maintain strong, personal relationships with its customers and local communities. A large portion of the recent growth of Duffy Insurance has come by way of the acquisition of other Massachusetts independent insurance agencies. The property and casualty insurance agency has office locations in Lynn, Gloucester, Peabody, Lowell, Chelmsford, Georgetown, Marblehead and Salem, Massachusetts.
