What Our Clients Say About Us

“Calahan Construction Services has a well-grounded team who work hard and understand our business. While they offer the typical architectural and construction skillsets, they also understand and have valuable real-world experiences inside the box, which adds considerable value for an owner.
Calahan has been very consistent in its project approach. They are careful in their planning, management, and organization of the project. And while the process is structured, they are also flexible and responsive to project change.
I’ve also found Calahan’s people to be highly focused on value. They produce the right amount of deliverables without adding drawings or specifications that aren’t needed. They are cognizant of budgets and pride themselves on delivering against budget.”
