Our Company History


Thomas A. Sullivan was born on May 8th, 1922 in Lawrence, Massachusetts. He attended Lawrence public schools, graduating from Lawrence High School in 1940. His military active duty started in 1943 where he served honorably in the US Army. He served oversees throughout Italy, where he was wounded in action on September 1944.  He received the purple heart for his service. Upon being honorably discharged in 1946, Thomas returned to his home city of Lawrence , MA, where he met and married Anna Abate.

In 1963 Thomas officially started T.A. Sullivan Agency from his Lawrence home on South Union street. He specialized in Home, Auto, and Life Insurance. He quickly developed a reputation of being an honest professional who always looked to help out his customers.

In 1970 Thomas tragically passed away after a very brief illness. His 7 years building T.A. Sullivan laid the foundation for Anna Sullivan to carry on his legacy and she continued to operate the agency in Lawrence expanding the product line and offering real estate services.

Today the agency services thousands of customers throughout Mass and NH, offering every possible insurance product as well as real estate services. The family tradition continues as the agency continues to expand and service more customers in the Merrimack Valley and Southern NH areas.
