“The Callahan team has consistently demonstrated a high level of professionalism, effective communication, and a great deal of pride in their work. Callahan’s commitment to providing exceptional service from preconstruction through completion was a key factor to the success of this project”

– Andrew Mahar, Founder & Managing Director, Anchor Line Partners

“The Callahan team demonstrated the highest level of professionalism from start to finish on our Lab renovations. The team was able to adapt quickly to the challenges of working within an occupied, sensitive environment.”

– Andrew Rovan, Senior Project Manager, Brandeis University

“Despite what we knew to be an aggressive design and construction timeline, your team remained flexible in their approach and candid in sharing concerns that could adversely impact the College. When we ran into unforeseen circumstances, the proactive, can-do attitude of your team was the boost we needed.”

– Deborah Jackson, President, Cambridge College 

“Callahan’s performance exceeded our expectations. The effectiveness and professionalism required Callahan to achieve success on this project well before construction started, with responsive, intelligent preconstruction services. A primary key to the success of the project was the integrity of Callahan’s team, from the executive level leadership to the final quality control personnel.”

– Patrick McMahon, VP, Development, Federal Realty
