“For the first time in [Morse Barnes Brown Pendleton] history, we were leaving the building where we’d started, and moving to a completely new environment. We knew how unsettling this experience might prove to be for us, and we knew how critical a role the construction management team would play in ensuring a successful project. We put our faith in the “Calnan Crew” and were not disappointed.  I have nothing but the highest regard for [JC&A’s] character, intelligence, integrity, expertise and standards. Their work, and that of their handpicked subs, took a vision of what might be and translated it into a reality of great beauty; they made a home for my Firm and our employees which we can enjoy every working day, a place to be proud of. I shall never forget the efforts of my Calnan Crew, nor them.” –  Laurie Macdonald, MBBP
