Bridgewater, MA Callahan Construction Managers (Callahan) was named one of the Largest Family Owned Businesses in Massachusetts, published by the Boston Business Journal, landing at #10. The list honors the Top 25 Largest Family Owned Businesses based on number of employees in Massachusetts and 2018 revenue. Earlier this year, Callahan ranked among the Top 25 Largest General Contractors, also published by the Boston Business Journal, coming in at #11.

Established in 1954 by Jack and Marie Callahan, the company quickly became a trusted name in construction management. Jack and Marie brought each of their five sons into the business as it grew, beginning the tradition that continues to this day.
