Company History

da_sullivan4In the fall of 1897 a carpenter's apprentice named Dennis A. Sullivan struck out on his own to form the D.A. Sullivan Co. Working out of his house with nothing more than a strong will to succeed and a supportive family, he quickly earned both experience for himself, as well as the respect of others in the construction field.

Much has changed in the construction industry in the past 100 years. Today technology is ever-changing, the market is fluctuating, schedules are compressed, and profit margins are razor-thin. However, some things remain the same. The pride of workmanship, commitment to quality, and the trustworthiness of the personnel at DAS has enabled us to sustain a growth and longevity that is rarely equaled in any business.

da_sullivan3Committed to our employees and to our work in Massachusetts, we take great pride in celebrating more than 116 years as one of the premier construction companies in the area. We look forward to the next century with a sense of responsibility to our founder. We strive to maintain his values that led to our successful past. This will serve as the cornerstone to a successful future.
