There is a reason the vast majority of our annual sales volume comes from repeat clients. We have proven time and again that the Callahan name is a trustworthy one and that our commitment to providing exceptional service from preconstruction through completion is a key factor to the success of every project we work on. Our expert preconstruction resources help minimize the risk of costly unforeseen changes to project scopes, and ensure a high-caliber finished product. We also have the unique ability to self-perform site work when it is the most cost-effective option, which is beneficial for site logistics, overall project duration, and managing horizontal infrastructure.
Callahan Construction Managers is a full service construction management firm with strong partnerships and great people.
With over 70 years serving the Northeast, we are one of the largest open shop, family-owned construction management companies in the region. We provide our clients with a wide range of preconstruction and construction management services, across market segments including life sciences, multifamily residential, senior housing, hospitality, corporate interiors, retail, educational, and other markets.
The Callahan StoryThe building of a strong foundation
Jack and Marie Callahan established John T. Callahan & Sons, Inc. in 1954 and eventually all five of their sons came into the family business after college. The company was founded on the principle that honesty, service, and care for customers would establish a successful company. Over the next 25 years the company grew steadily, servicing notable clients across the East Coast.
That legacy and those principles live on in Callahan Construction Managers and today these values touch every part of our business, from building deep relationships with our clients, to supporting the professional growth of our employees. Top quality work, and a commitment to treating our employees, subcontractors, and clients like family. It’s how we’ve built our reputation as a leader in the industry, and it’s the foundation that will carry us forward.
The Callahan Difference Why does 85% of our business come from repeat clients?
“We appreciate the Callahan’s team-oriented approach and management of each project. Whenever there have been issues over the course of a job, the approach is one of working together to find the solution that is for the best interest of the success of the project.”
– Ed SanClemente, Vice President of Development at LCB Senior Living
